Question

ULTIPLE CHOICE: Select the expression that is equivalent to 2x²+11x - 21 over x+3 by dividing. A. 2x+5- 6 over x+3
b. 2x + 17 - 20 over x+3
C. 2x + 17 - 36 over x²+3x
d. 2x+5 - 36 over x+3​

Answer 1

By using long division to the polynomial, we obtain the expression $\frac{2x^2+11x-21}{x+3}$ as $2x+5-\frac{36}{x+3}$.

Given expression;

$\frac{2x^2+11x-21}{x+3}$

For the given expression applying polynomial long division, we get;

⇒ $\frac{2x^2+11x-21}{x+3}$

$=2x+\frac{5x-21}{x+3}$

$=2x+5+\frac{-36}{x+3}$

$=2x+5-\frac{36}{x+3}$

Hence, by using long division on the polynomial we get an expression equivalent to $\frac{2x^2+11x-21}{x+3}$ as $2x+5-\frac{36}{x+3}$.
