Solve the following equation: x^2 - 11x + 18 = 0

Use the factorisation method.

Step 1: Rewrite (x + __ )(x + __ ) = 0

Step 2: We need to fill in the blanks. The numbers we require are -2 and -9.

Step 3: We need the values of x, so that when the brackets are multiplied together, the answer is zero.

So, x = 2 or x= 9.

Step 4: Substitute in the values of x into the original quadratic and check you have the right answer. You should get zero both times.
