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

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.

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

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

9x^2-36x+35
