Factor f (x) = -8x^4-16x^2

8x^2 (x^2-8)

Step-by-step explanation:

you find the lCM

the LCM of 16 and 8 is 8

the LCM of x^2 and x^4 is x^2

in all the LCM is 8x^2

8x^4/8x^2=x^2

you divide the numbers and subtract the powers of the variables

-16x^2/8x^2 = - 8 the you put everything in a distribution form
