The rest theorem calculator is loose on line tool that helps you to calculate the remainder of given polynomial expressions through the rest theorem.

Our aspect theorem calculator offers little by little calculations of the aspect of division. right here you can apprehend a way to locate the the rest of a polynomial the use of the formulation.

What is the the rest Theorem?

In algebra, the remainder theorem or little Bezout’s theorem is an utility of Euclidean division of different expressions, that is located by way of Etienne Bezout. It states when an expression is split via a element x-j, then the the rest of the division is same to f(j).

How to discover Remainders with out Calculator

when the polynomial f(x) is divisible by using a linear issue of the form x-j, the theorem will be utilized by the remainder theorem calculator. if you want to do those calculations by hand, then comply with the instructions beneath and use them to resolve the rest of the polynomial expression in a few minutes.

  • The polynomial f(x) is used because the dividend, and the linear expression is used as the divisor.
  • The form of the linear expression need to be x-j.
  • Then, the remaining value of the polynomial will become m(x).
  • consequently, insert the cost of c into the polynomial and compare it to attain the the rest cost.

Example

Solve \( (x^4 + 8x^3 - 6x^2 + 5x - 11) \) with denominator \( (x + 2) \) using the remainder theorem.

Solution: Given values are

$$f(x) = x^4 + 8x^3 - 6x^2 + 5x - 11$$

Since \( x + 2 \) is in the form of \( x - (-2) \),

Then \( c = -2 \)

$$f(-2) = (-2)^4 + 8(-2)^3 - 6(-2)^2 + 5(-2) - 11$$

$$= 16 + 8(-8) - 6(4) + 5(-2) - 11$$

$$= 16 - 64 - 24 - 10 - 11$$

$$= -93$$

The remainder of the given expression is \( -93 \).

Property Formula Example Calculation
Remainder Theorem If a polynomial f(x) is divided by (x - c), the remainder is f(c). For f(x) = x² - 5x + 6, remainder when divided by (x - 2) is f(2) = 2² - 5(2) + 6 = 4 - 10 + 6 = 0.
Divide Polynomial by Linear Binomial Remainder = f(c) If f(x) = x³ - 4x² + 3x - 2 and the divisor is (x - 1), then f(1) = 1³ - 4(1)² + 3(1) - 2 = 1 - 4 + 3 - 2 = -2.
Dividing Polynomial by (x - c) The remainder is the value of the polynomial at x = c. For f(x) = 2x³ + 3x² - x - 5 and divisor (x + 1), calculate f(-1) = 2(-1)³ + 3(-1)² - (-1) - 5 = -2 + 3 + 1 - 5 = -3.
Finding the Remainder with Synthetic Division Perform synthetic division with c as the value. If f(x) = x² + 3x - 4 and dividing by (x - 1), synthetic division gives remainder = f(1) = 1² + 3(1) - 4 = 0.
Factor Theorem If f(c) = 0, then (x - c) is a factor of f(x). For f(x) = x² - 5x + 6, since f(2) = 0, (x - 2) is a factor of f(x).
Dividing Polynomial by Non-Linear Polynomial Remainder is obtained by applying the Remainder Theorem at appropriate values. If f(x) = x³ - x² + 2x - 3 and divisor (x² - 1), we find the remainder by evaluating at appropriate x values (use direct substitution of values in polynomial).
Remainder of Polynomial Divided by (x - c) Remainder is the value of the polynomial at x = c. If f(x) = 2x⁴ - 3x³ + x - 4 and divisor (x - 1), then f(1) = 2(1)⁴ - 3(1)³ + 1 - 4 = 2 - 3 + 1 - 4 = -4.
Evaluating Polynomial at Specific Value Substitute the value of x directly into f(x). For f(x) = x² + 2x + 1, remainder when divided by (x - 1) is f(1) = 1² + 2(1) + 1 = 4.
Remainder for Polynomial Division Find the remainder by substituting x = c into the polynomial. For f(x) = x⁴ - 4x³ + 3x² - 2x + 1 and divisor (x - 3), f(3) = 3⁴ - 4(3³) + 3(3²) - 2(3) + 1 = 81 - 108 + 27 - 6 + 1 = -5.
Using Remainder Theorem for Evaluation Substitute c into f(x) to evaluate the remainder. If f(x) = x³ - 6x² + 11x - 6 and divisor (x - 2), f(2) = 2³ - 6(2²) + 11(2) - 6 = 8 - 24 + 22 - 6 = 0.

FAQs.

What is the Remainder Theorem.

Remainder Theorem postulates that when dividing a polynomial by a first-degree divider, the residual of said division equals the value of the polynomial at the designated c.

How does the Remainder Theorem work.

To apply the Remainder Theorem, replace the value c into the polynomial. The result is the remaining when the polynomial is divided by x-c.
