Question

Factorise :- (2x²+13 x+20)÷(x+4)

Answer 1

Answer:

2x+5

Step-by-step explanation:

=2x^2+8x+5x+20

=2x(x+4)+5(x+4)

=(x+4)(2x+5)

(x+4)(2x+5)÷(x+4)

=2x+5

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

$\frac{(2x + 5)(x + 4)}{(x + 4)}$

$2x + 5 = 0 \\ = > 2x = - 5 \\ = > x = \frac{ - 5}{2}$
