Question

The expression below is the factorization of what trinomial?
(5x + 6)(3x - 2)
O A. 15x2 + 8x+12
B. 15x2 + 4x-12
O C. 15x2 + 4x+12
О
D. 15x2 + 8x-12

Answer 1

Answer:

D. 15x^2 + 8x - 12

Step-by-step explanation:

To solve this problem, simply expand the factorization and find the polynomial.

5x * 3x = 15x2

5x * -2 = -10x

6 * 3x = 18x

6 * -2 = -12

You are left with 15x2 - 10x +18x - 12, but you need to combine like terms, leaving you with the correct answer: 15x2 + 8x - 12.

Answer 2

Answer:

D.

Step-by-step explanation:

(5x+6)(3x-2)=5x*3x-5x*2+6*3x-6*2=15x^2-10x+18x-12=15x^2+8x-12
