WebExample 5: combining HCF / GCF and difference of two squares. Fully factorise. x 3 – 64x. Be careful, this one is not the difference of two squares! We first need to find the highest or greatest common factor ( x) and write it outside of a single bracket. x (x 2 – 64) Write down two brackets with the x at the front. 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) black velcro shoes for boys
