 2 TERMS Missing 1st Term 3x - 12 = 0Not Quadratic! (linear) Solve for 1 answer x = 12 x = 4 Missing 2nd Term Use Square Root Method Missing 3rdTerm x2 + 3 = 0you forgot to factor out the common “x” isolate x2 x = 12 both sides isolate squared binomial  both sides ALL 3 TERMS By Factoring   By Completing the Square 2x2 - 6x - 3 = 0 coefficient of x2 must be 1: divide both sides by 2: complete the square: add (½B)2 to both sides: write as a binomial squared: use Square Root Method: B2-4ac is called the discriminant 1) if B2-4ac is positive: 2 real roots 2) if B2-4ac is negative: 2 complex roots 3) if B2-4ac = 0: 1 real root (twice) Quadratic Formula Remember: You must check both solutions when you make a non-quadratic equation quadratic!
