Question

BRAINLIESTTT ASAP! PLEASE HELP ME :) Simplify (9k^6 + 8k^4 – 6k^2)(4k^2 – 5)

Answer 1

Answer:

$\large \boxed{36k^{8} - 13k^{6} - 64k^{4} + 30k^{2}}$

Step-by-step explanation:

(9k⁶ + 8k⁴ - 6k²)(4k² - 5)

The easiest method is probably to use long multiplication.

9k⁶ + 8k⁴ - 6k²

4k² - 5

36k⁸ + 32k⁶ - 24k⁴

        -  45k⁶ - 40k⁴ + 30k²

36k⁸ -  13k⁶ - 64k⁴ + 30k²

$\text{The product of the polynomials is \large \boxed{\mathbf{36k^{8} - 13k^{6} - 64k^{4} + 30k^{2}}} }$

Answer 2

Answer:

$\displaystyle 30k^2 - 64k^4 - 13k^6 + 36k^8$

Step-by-step explanation:

$\displaystyle 30k^2 - 64k^4 - 13k^6 + 36k^8 = -24k^4 + 32k^6 + 32k^8 + 30k^2 - 40k^4 - 45k^6$

I am joyous to assist you anytime.
