Question

Factorise 2x^2 +13x + 20 and divide it by (x+4)

Answer 1

Step-by-step explanation:

$2 {x}^{2} + 13x + 20 \\ = 2 {x}^{2} + 8x + 5x + 20 \\ = 2x(x + 4) + 5(x + 4) \\ = (x + 4)(2x + 5)$

Now, I am going to divide :-

$2 {x}^{2} + 13x + 20 \div (x + 4) \\ = (x + 4)(2x + 5) \div (x + 4) \\ = 2x + 5$

Because, x+4 and x+4 will cancel each othet.
