Do you graph with the quadratic formula
WebWith the quadratic equation in this form: Step 1: Find two numbers that multiply to give ac (in other words a times c), and add to give b. Example: 2x2 + 7x + 3. ac is 2Γ3 = 6 and b is 7. So we want two numbers that multiply together to make 6, and add up to 7. In fact 6 and 1 do that (6Γ1=6, and 6+1=7) WebMay 17, 2011 Β· The graph of a quadratic function is a parabola.
