Solving Equations by Using the Zero Product Rule

This material is review from MAT 1175.

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