How do you apply the FOIL method to the expression (x + 2)(x + 3)?

Back

Multiply the First terms: x * x = x^2; Outside terms: x * 3 = 3x; Inside terms: 2 * x = 2x; Last terms: 2 * 3 = 6. Combine to get x^2 + 5x + 6.

What are the 'Last' terms in the FOIL method?

Back

The 'Last' terms are the last terms of each binomial that you multiply together.

How do you simplify the expression (x - 1)(x - 8) using the FOIL method?

Back

Multiply: First: x*x = x^2; Outside: x*(-8) = -8x; Inside: -1*x = -x; Last: -1*(-8) = 8. Combine to get x^2 - 9x + 8.
