Solve quadratic equations by factorising using formulae and completing the square.
Solve each of these equations. Let us now solve the equation by Completing The Square and by using the Quadratic. When the coefficient of x2 is greater than 1 and we cannot simplify the quadratic equation by finding common factors we would need to consider the factors of the coefficient of x2 and the factors of c in order to get the numbers whose sum is b.
