Question

factorize 2x^2+15x+7

Answer 1

Find two numbers whose sum = 15 and product = 2×7 = 14.

The numbers are 14 and 1.

2x^2 + 15x +7

= 2x^2 + 14x + 1x + 7

= 2x(x+7) + 1(x+7)

= (2x+1) (x+7)

Answer 2

Answer:

2x^2+15x+7=(2x+1)(x+7)

Step-by-step explanation:

2x^2+15x+7

2x^2+x+14x+7

x(2x+1)+7(2x+1)

(2x+1)(x+7)
