Find solutions to quadratic equations
Web4.3 Solution of Quadratic Equations by Factorisation. A real number α is called a root of the quadratic equation ax 2 + bx + c = 0, a ≠ 0 if a α 2 + bα + c = 0. We also say that x … 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)
