Answer:

Given : 15x2+2x−8

We can further write it as 

15x2+2x−8=15x2−10x+12x−8

By taking out the common terms

15x2+2x−8=5x(3x−2)+4(3x−2)

So we get,

15x2+2x−8=(5x+4)(3x−2)

Step-by-step explanation:

Factoring 15x2-3x-8

The first term is, 15x2 its coefficient is 15 .

The middle term is, -3x its coefficient is -3 .

The last term, "the constant", is -8

Step-1 : Multiply the coefficient of the first term by the constant 15 • -8 = -120

Step-2 : Find two factors of -120 whose sum equals the coefficient of the middle term, which is -3 .

-120 + 1 = -119

-60 + 2 = -58

-40 + 3 = -37

-30 + 4 = -26

-24 + 5 = -19

-20 + 6 = -14

-15 + 8 = -7

-12 + 10 = -2

-10 + 12 = 2

-8 + 15 = 7

-6 + 20 = 14

-5 + 24 = 19

-4 + 30 = 26

-3 + 40 = 37

-2 + 60 = 58

-1 + 120 = 119
