MAT 095 Lecture Notes - Lecture 29: Quadratic Formula
Document Summary
Provide a generalization to each of the terms listed in this section. Quadratic formula: this is the formula for the quadratic formula: x = b b2 4ac. Quadratic formula derivation ax2 + bx + c = 0 ax2. 0 a a bx a x2 + b a x + = 0 c a c a c a b x + x + c a b2. 2a x = b b2 4ac. 2a x2 + x2 + x + b a b a b a x2 + (cid:18)x + (cid:18)x + s(cid:18)x + x + x + b. 6y + 3 = 4y2 (6y + 3) (6y + 3) = 4y2 (6y + 3) 4 y = y = y = y = y = Discriminant: this is the formula for the discriminant: b2 4ac, the discriminant helps give one of three following pieces of information:
