... When we graph a system of two linear equations in two variables, one of the following three outcomes will occur. 1. The lines have one point in common, and that point is the only solution of the system. Any system that has at least one solution is said to be consistent. 2. The lines are parallel, w ...

... written at the other end of the brackets. Example 1: Factorise x2 – 9x – 10. Solution: We need to find two numbers that multiply to make -10 and add to make -9. These numbers are -10 and 1. Therefore x2 – 9x – 10 = (x – 10)(x + 1). General quadratics: Factorising quadratics of the form ax 2 bx c ...
