How to do foils in algebra

Leno4ka [110]

Foils stands for first, outer, inner, last.

For example:

(3x + 5)(2x + 3)

Multiply the firsts together.

3x * 2x = 5x²

Now multiply the outer together.

3x * 3 = 9x

Now multiply the inners.

5 * 2x = 10x

Now multiply the lasts.

5 * 3 = 15

so the answer would be:

5x² + 9x + 10x + 15
5x² + 19x + 15

Hope this helps :)
