Question

Factor completely 2x^2+13x+20

Answer 1

(2x+5)(x+4)

Explanation:

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

Answer 2

(2x+5)(x+4)

Explanation:

2x²+13x+20

_5_+_8_=13

_5_×_8_=(2x20)

now it can be re-written as

2x²+5x+8x+20

which can be factored to be:

(2x+5)(x+4)
