Litzy Mullins · Answer 1

Since both terms are perfect squares, factor using the difference of squares formula, a2-b2 = (a+b) (a-b) where a=8x and b=11

.

(8x+11) (8x-11)

Justin Blake · Answer 2

64x^2-121

Rewrite 64x^2 as 8x^2

Rewrite 121 as 11^2

Now you have 8x^2-11^2

Use the difference of squares formula, a^2 - b^2 = (a + b) (a-b) where a = 8x and b = 11

Answer is:

(8x+11) (8x-11)
