How to factor a binomial by factoring out the GCF as well as by difference of two squares

What is the greatest common factor of -3 and 48?

• 3

• 1

• -3

• 48

After factoring out the GCF from the expression, what is the resulting expression?

• X^2 + 16Y^2

• X^2 - 16Y^2

• X^2 + 48Y^2

• X^2 - 48Y^2

What is the result of dividing 48 by -3?

• -16

• 16

• 48

• -48

Which formula is used to factor the expression X^2 - 16Y^2?

• a^2 + b^2 = (a - b)(a + b)

• a^2 - b^2 = (a - b)(a - b)

• a^2 - b^2 = (a + b)(a - b)

• a^2 + b^2 = (a + b)(a - b)

What are the factors of the expression X^2 - 16Y^2?

• (X + 4Y)(X + 4Y)

• (X - 4Y)(X - 4Y)

• (X + 4Y)(X - 4Y)

• (X - 4Y)(X + 4Y)
