multiply
(-x-1)(-4x^2-2x+2)
Multiply EVERY term in the second bracket by -x; then do the same with the -1. Gather all the like terms together: all the exponents, then all the x terms and then all the numbers.
Would the answer here be 8x^2+4x?
(-x-1)(-4x^2-2x+2)
= 4x^3+2x^2-2x+4x^2+2x-2
=4x^3+6x^2-2
To multiply the expression (-x-1)(-4x^2-2x+2), we can use the distributive property.
First, multiply -x with each term inside the second parentheses:
-4x^2 * -x = 4x^3
-2x * -x = 2x^2
2 * -x = -2x
Next, multiply -1 with each term inside the second parentheses:
-4x^2 * -1 = 4x^2
-2x * -1 = 2x
2 * -1 = -2
Now, let's combine like terms:
4x^3 + 2x^2 - 2x + 4x^2 + 2x - 2
Combine the like terms:
4x^3 + (2x^2 + 4x^2) + (-2x + 2x) - 2
Simplify further:
4x^3 + 6x^2 - 2
Therefore, the product of (-x-1)(-4x^2-2x+2) is 4x^3 + 6x^2 - 2.
