Help! How do I solve quadratic equations?
Quadratic equations contain the term x2 and they can normally be written in the format of:ax2 + bx + c = 0. You can solve these equations by using a technique called factorisation. Factorised quadratic equations take the form of (x + d)(x+e). For example: 2x2 + 10x + 12 = 0. Divide each side by 2. x2 + 5x + 6 = 0. Find 2 numbers (d and e) which multiply to make 6 and sum to make 5. 2 x 3 = 6 and 2 + 3 = 5. Write it in the form of (x + d)(x+e) = 0. (x + 2)(x + 3) = 0. If 2 things multiply to make 0, then one of them has to be 0!(x+2) = 0 or (x+3) = 0 x = -2 or x = -3
