Question

simplify
a) (x^2+7x+12)÷(x+3)
b)(x-3)^2 by 4x^2-25 ÷ (x^2-x-6) by 2x-5

Answer 1

Hello Friends ✌
Here is u r Ans ➡

$= a) > (x {}^{2} + 7x + 12) \div (x + 3)$

$= \frac{x {}^{2} + 7x + 12}{x + 3}$

$= \frac{x {}^{2} + 4x + 3x + 12 }{x + 3}$

$= \frac{x \times (x + 4) + 3(x + 4)}{(x + 3)}$

$= \frac{(x + 4) \times (x + 3)}{x + 3}$

$= \frac{(x + 4) \times (x + 3)}{(x + 3)}$

$reduced \: (x + 3)$

$= x + 4$
