Question

64-125x^6 help pls!!!

Answer 1

(4 -- 5x^2)(16 + 20x^2 + 15x^4)

Explanation:

start with factoring out -- 1

After factoring out −1 we have: -25x^6 + 64 = --1(125x^6 -- 64)

To factor 125x^6 − 64 we can use difference of cubes formula

After putting I=5x^2 and II=4 , we got:

125x^6 − 64=(5x^2 − 4)(25x^4 + 20x^2+16) which is basically your answer.

hope this helps! have an amazing day <3
