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: 2x 2 + 7x + 3. ac is 2×3 = 6 and b is 7. So we want two numbers that … WebINSIDE: 5 × x = 5 x. LAST: 5 × 4 = 20. The next step is to add these together: 2 x 2 + 8 x + 5 x + 20 is the same as 2 x 2 + 13 x + 20. So the original equation (2 x + 5) ( x + 4) = 0 becomes: 2 x 2 + 13 x + 20 = 0. …
