Answer:

(5x^2+2)(3x - 1)

Step-by-step explanation:

Factor 15x^3-5x^2 + 6x – 2 by grouping

15x^3 - 5x^2 + 6x - 2

In grouping method we group first two terms and last two terms

(15x^3 - 5x^2) + (6x - 2)

Take out GCF from each group

5x^2(3x - 1) + 2(3x - 1)

Now we factor out 3x-1

(5x^2+2)(3x - 1)

Need help with this equation
NeX [460]

Answer:

D. 28x + 14 + 3 = - 67

Step-by-step explanation:

Given 7 ( 4x + 2 )  + 3 = - 67

our first step would be to distribute the 7

7 * 4x = 28x

7 * 2 = 14

we would be left with 28x + 14 + 3 = -67 which corresponds with "D"
