#### Finding the roots of a quadratic equation needing simplification

This demonstrates how some quadratic equations need to be simplified and put in standard form before the quadratic expression can be factored so the factors can be set to zero and solved.

#### Finding the roots of a quadratic equation with leading coefficient greater than 1

This is a quadractic equation that can be factored to solve it. The zero product property allows writing the factors each equal to 0 and then solving those linear equatioins.

#### Finding the roots of a quadratic equation with leading coefficiant 1

This applies the factoring methods learned previously to solving a quadratic equation in standard form, that is with all th eterms on the left of the equals sign and 0 on the right

#### Finding the roots of a quadratic equation of the form ax^2 + bx = 0

This type of equation is solved by factoring a GCF from both terms once the proper form is achieved. Then the zero product property allows the separation of the two factors into two solvable linear…
