1. Rewrite the numbers so they have the same bases i.e. 8 2 = (2 3 ) 2

2. Example 1: Two Linear Equations Page 29 exercise 3A

3. Factorise and Sketch… y = x 2 – 5x - 6y = 2x 2 + 7x + 33x 2 + 5x = 2y = x 2 – 9y = x 2 + 3x + 1

4. Example: 1. Choose the linear equation and rearrange to make either x or y the subject 2. Substitute into the quadratic equation and simplify 3. Solve the resulting quadratic equation 4. Substitute back into rearranged linear equation to get other values

5. Page 31 exercise 3C 1. Choose the linear equation and rearrange to make either x or y the subject 2. Substitute into the quadratic equation and simplify 3. Solve the resulting quadratic equation 4. Substitute back into rearranged linear equation to get other values
