Question

Helpp meeeeeeeee  a^12-4a^2 factor does ths work?

Answer 1

a¹² - 4a² 

pull the a² factor out from both terms

= a²(a¹⁰-4)

can be factored further

= a²(a⁵-2)(a⁵+2)

 

Answer 2

Hi Jackson,

 

You have to look for the largest common terms and take them out. . . a^2 is the largest term that is common to both terms in the expression, so . .

 

a^2(a^10 - 4)

 

You can check the answer by multiplying what's inside the parentheses by "a" squared.
