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