Quiz 8-1 graphing quadratic equations. Things To Know About Quiz 8-1 graphing quadratic equations.

This is how the solution of the equation 2 x 2 − 12 x + 18 = 0 goes: 2 x 2 − 12 x + 18 = 0 x 2 − 6 x + 9 = 0 Divide by 2. ( x − 3) 2 = 0 Factor. ↓ x − 3 = 0 x = 3. All terms originally had a common factor of 2 , so we divided all sides by 2 —the zero side remained zero—which made the factorization easier. The graph of the quadratic function is in the form of a parabola. The quadratic formula is used to solve a quadratic equation ax 2 + bx + c = 0 and is given by x = [ -b ± √(b 2 - 4ac) ] / 2a. The discriminant of a quadratic equation ax 2 + bx + c = 0 is given by b 2-4ac. This is used to determine the nature of the zeroes of a quadratic function.Finding angles of triangles.
