Which identity could be used to rewrite the expression x^9-8 a. two squares b. difference of squares c. difference of cubes d. quadratic formula

We are given expression :.

Let us write 8 in factored form.

8 could be factored as 2×2×2.

2×2×2 = .

Let us convert also in terms of cube of a term.

could be written as the factors of .

.

Therefore, .

Which shows the difference of cubes.

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides

step-by-step explanation:

4
