Simple Explanation of Factorising Quadratics
Factorising is the reverse of expanding (multiplying out) brackets, it simplifies an expression. A quadratic expression has the general form ax2 + bx + c where a, b and c are numbers, the highest power of x in quadratic expressions is 2. “a” is the coefficient of x2, b is the coefficient of x, and c is the constant term. These numbers can be positive or negative. The numbers b and c can also be zero.
