Solving Quadratic Formula using the discriminant
2
Quadratic formula using the discriminant Examples: Step 1: Write equation in Standard Form Ax ² + Bx + C = 0 x² + 4x + 3 = 0 4x² + 8x + 3 = 0 3x² + 6x = 0
3
Quadratic formula using the discriminant Step 2: Find A,B and C x² + 4x + 3 = 0 C= 3 3x² + 6x = 0 A=3 B= 6 C= 0 4x² + 8x + 3 = 0 A=4 B= 8 C= 3 A=1B= 4
4
Quadratic formula using the discriminant Is the discriminant. If b²-4ac is positive, then the equation has 2 answers. If b²-4ac is 0, then the equation has 1 answer. If b²-4ac is negative, then the equation has no real solution. Rational Irrational Rational
