Choose the inequality type and enter your expression (e.g., x+1>3) to get the step-by-step solution of inequality and a visual number line representation of the solution.
This inequality calculator solves linear and quadratic inequalities in a smooth way. Solving inequalities has now become just too simple when all the steps are represented in detail. The graphical representation of the inequality, whether it is linear or quadratic is also elaborated by this graphing inequalities calculator.
Inequality is a statement of an order greater than, greater than or equal, less than, or less than or equal to between the corresponding numbers or algebraic expressions.
For example:
2 + 4 < 7, 3y - 7 > 8
The following operators are used to solve inequalities when you are applying the inequalities operations in the compound inequality calculator. You need to understand these operators.
The inequality values can be represented by the four of the following operators. It is easy to understand the ” >” Greater than and “<” Less than. But when we are having >= Greater than equal or <= Less than and equal, then it becomes difficult to understand. It means there are some values where equal values come and at other points, we are getting less than or greater than values.
There are certain rules that are used to solve inequalities and these rules are also followed by our compound inequality calculator when solving inequalities. These rules apply to the inequalities whether it is linear or quadratic inequalities.
When multiplying a negative real number on each side of the inequality, it changes the inequality equations direction.
This can be understood by the following example:
a>b and c<0. Then a*c< b*c
When multiplying a positive real number on each side of the inequality, It doesn't change the inequality equation direction.
This can be understood by the example:
a>b and c>0. Then a*c> b*c.
When dividing a negative real number on each side of the inequality, it changes the inequality equation's direction.
This can be understood by the example:
a>b and c<0. Then a/c< b/c.
When dividing a positive real number on each side of the inequality, not change the direction of the inequality equation.
This can be understood by the example
a>b and c>0. Then a/c> b/c.
Adding the same real number(positive or negative) on each side of the inequality doesn't have any effect on the direction of the inequality.
The inequality solver has no effect:
if a>b and c R, then a+c>b+c.
Subtracting the same real number(positive or negative) on each side of the inequality does have any effect on the direction of the inequality.
The inequality solver has no effect:
if a>b and c R, then a-c>b-c.
When Squaring each positive side of the inequality, then it does not affect the direction of the inequality
The inequality is represented as:
When Squaring each of the negative sides of the inequality, then it does change the direction of the inequality:
ab2
When Inverting each no zero side of an inequality changes, then the direction of the inequality:
a1/b
Whenever you are asked, how do you solve inequalities? suggest the above-written or the use of an efficient inequality solver that can resolves all the inequalities by implementing the rules of the inequalities.
When solving a linear inequality of the type “a.x>b”,then the linear inequalities calculator is an effective way to solve such inequality. For example when you are entering an inequality like 5x>7, the linear calculator shows the result like x>7/5 and represents. The graph inequality calculator portrays the graphical representation of the inequality. 
When solving quadratic inequality of the form ax2+bx c>0, the process is simple when you have real roots. Using quadratic inequalities calculator is the best solution to get step-by-step calculation of inequality. When we put the x2+6x+9>0 in the compound inequalities calculator, we find the roots x>-3 and x<3. Both the roots are real in its nature, and when solving and graphing inequalities of the quadratic equation x2+6x+9>0. The straight line is represented as the graphs lies between values of -3 >x<-3.
Solving the Rational Inequality:
Solving inequalities with fractions of the types (x+1)/(3−x)>2 can be simple and efficient when using the rational inequality calculator. The graph of the rational fraction helps to understand the inequality (x+1)/(3−x)>2 in a blink of eye. The answer of the the above mentioned rational fractions is 5/3
