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 2×3 = 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 (6×1=6, and 6+1=7) How do we find 6 and 1?
