WebExample 1: perfect square. Find the closest perfect square by dividing the coefficient of x by 2. The coefficient of x is 8, so when we divide this by 2, we get 4. 2 Expand the perfect square expression. 3 Compare the constant term in the perfect square to the original expression, and adjust as needed. WebFirst off, remember that finding the x-intercepts means setting y equal to zero and solving for the x-values, so this question is really asking you to "Solve 4x 2 − 2x − 5 = 0 ".. Now, let's start the completing-the-square process. To begin, we have the original equation (or, if we had to solve first for "= 0", the "equals zero" form of the equation).). In this case, we were …

WebLearn and revise how to solve quadratic equations by factorising, completing the square and using the quadratic formula with Bitesize GCSE Maths Edexcel. A quadratic equation with real or complex coefficients has two solutions, called roots. These two solutions may or may not be distinct, and they may or may not be real. It may be possible to express a quadratic equation ax + bx + c = 0 as a product (px + q)(rx + s) = 0. In some cases, it is possible, by simple inspection, to dete…
