Question

What is the product of (3x-7)(3x-5)

Answer 1

3x(3x-5)-7(3x-5)

9x^2-15x-21x+35

9x^2-36x+35

Answer 2

The answer is 9x² - 36x + 35

FOIL Method or Box Method can be useful in solving this problem.

First Terms Product: 3x × 3x = 9x²

Outside Terms Product: 3x × -5 = -15x

Inner Terms Product: -7 × 3x = -21x

Last Terms Product: -7 × -5 = +35

Combining like terms results in the answer given above.
