Solving Equations by Using the Zero Product Rule

This material is review from MAT 1175.

$\rhd$ Solving quadratic equations by factoring (6:21) Sal solves $s^2-2s-35 = 0$
$\star$ Solving quadratic equations with leading coefficient 1 (i.e., of the form $x^2 +bx+c = 0$ ).
$\rhd$ Solving quadratic equations with leading coefficient not equal to one (4:35) Example solved: $6x^2 - 120x + 600 = 0$ .
$\star$ Solving quadratic equations with leading coefficient not equal to one, i.e., of the form $ax^2 +bx +c = 0$ where $a \neq 1$ .
$\rhd$ Solving quadratics using structure (3:55) Solve the equation $(2x-3)^2 = 4x-3$ by making the substitution $p = 2x-3$ .
