Part 1: Using the guess and check method.
Step 1: Simplify (2x + 3)(3x 5)
So far, we have only factored problems that were either special, or the leading coefficient has
been 1 (x2 + bx + c). Today, our leading coefficient
Factoring is undoing multiplication, almost like division.

Investigation: Square root method and Zero Product Property
Part 1: Solve equations using the square root method.
Step 1: When you solve an equation by taking the square root of both sides,
ALWAYS remember that you will get 2 answers.
Example: Solve x2 =
