Question

Simplify.(picture provided, thank you so much)​

Answer 1

-5x^4(-3x^2 + 4x -2)

Multiply the number on the outside by each number inside the parentheses:

-5x^4 x -3x^2 = 15x^6

-5x^4 x 4x = -20x^5

-5x^4 x -2 = 10x^4

Now combine them in order of exponents:

15x^6 - 20x^5 + 10x^4

Answer 2

Answer:

Step-by-step explanation:

$-5x^{4}*(-3x^{2} + 4x - 2) = (-5x^{4} * -3x^{2})+(-5x^{4}*4x)-(-5x^{4}*2)\\\\=15x^{4+2}+(-20x^{4+1})-(-10x^{4})\\\\=15x^{6}-20x^{5}+10x^{4}$
