WebTo solve this, you would use the zero product property. If you make one of the parentheses equal to zero then the whole left side is equal to zero (because zero multiplied by anything is zero). So you'd set the first set of parentheses like so: (x-2)=0. Then to isolate "x", you would add 2 to both sides to get x=2. 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?
