Recap: Solving Quadratic Equations-All Methods

trinomial is factorable

set equal to 0 before solving

take GCF out (if there is a GCF)

find factors using

set each factor equal to 0 and solve

do not set equation equal to 0

factor the trinomial

take the square root of both sides

solve for x

set equation equal to 0

take out GCF

set both factors equal 0

solve for x

do not set equal to 0

isolate the square term

divide by the coefficient of x², if any

take square root of both sides

solve for x

can be used with any quadratic trinomial

set equation equal to the c value

complete the square using (b/2)²

factor the trinomial

take the square root of both sides

solve for x

set up equation in standard form

substitute a, b and c values into the formula

solve for x
