Choose the correct simplification of the expression −4x2(6x − 5x2 − 5). 20x4 24x3 20x2 −9x4 2x3 − 9x2 20x4 − 24x3 20x2 −20x4 24x3 − 20x2.

20x4−24x3+20x2

Step-by-step explanation:

when simplifying you first distribute the -4x^2. This will result in -24x^3, 20x^4, and 20x^2

20 x^4 - 24 x^3 + 20 x^2 is the only correct answer however not the best simplification.

Step-by-step explanation:

Simplify the following:

-4 x^2 (-5 x^2 + 6 x - 5)

Hint:  Factor a minus sign out of -5 x^2 + 6 x - 5.

Factor -1 out of -5 x^2 + 6 x - 5:

-4 x^2×(-(5 x^2 - 6 x + 5))

Hint:  Multiply -4 and -1 together.

-4 (-1) = 4:

 4 x^2 (5 x^2 - 6 x + 5)

instagram is better than go there instead lol

step-by-step explanation:

35x 3= 105

step-by-step explanation:

35+35= 70   70 + 35= 105
