Question

factor the expression. 15x^2 – 16xy 4y^2

a. (3x 2y)(5x – 2y)

b. (3x – 2y)(5x – 2y)

c. (3x 2y)(5x 2y)

d. (3x – 2y)(5x 2y)

Answer 1

If you would like to factor the expression 15x^2 - 16xy + 4y^2, you can do this using the following steps:

15x^2 - 16xy + 4y^2 = (5x - 2y) * (3x - 2y) = 5x * 3x - 5x * 2y - 2y * 3x + 2y * 2y = 15x^2 - 10xy - 6xy + 4y^2 = 15x^2 - 16xy + 4y^2

The correct result would be b. (5x - 2y) * (3x - 2y).
