What is (x^2- 5x-4) (-2x+4) simplified

=-2x^3 + 14x^2 - 12x - 16

Step-by-step explanation:

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

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

=-2x^3 + 14x^2 + 10x^2 - 20x + 8x - 16

=2x^3 + 14x^2 - 12x - 16

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

answer is because 4×10=40

and 98×4= is 392

40,392
