Question

rewrite without parentheses.
-9n^{4}xleft(6n^{6}+7n^{5}x^{2}-8x^{2}
ight)
simplify your answer as much as possible.

Explanation:

Step1: Distribute -9n⁴x⁴

Multiply -9n⁴x⁴ with each term inside the parentheses:
-9n⁴x⁴ * 6n⁶ = -54n^(4+6)x⁴ = -54n¹⁰x⁴
-9n⁴x⁴ * 7n⁵x² = -63n^(4+5)x^(4+2) = -63n⁹x⁶
-9n⁴x⁴ * (-8x²) = 72n⁴x^(4+2) = 72n⁴x⁶

Step2: Combine like terms (if any)

Check for like terms (same variables with same exponents). Here, no like terms to combine.

Answer:

-54n¹⁰x⁴ - 63n⁹x⁶ + 72n⁴x⁶
