A a) Draw a graph of \( y=(2 x-3)(x-1) \) for the interval \( -2 \leqslant x \leqslant 4 \) (b) use your graph to solve. (i) \( 2 x^{2}-5 x+3=0 \) (il) \( 2 x^{2}=3 x+2 \)

Simplify the following: (1) \( \frac{x-1}{x^{2}+3 x+2} \div\left[\frac{x-3}{x+1}-\frac{x-4}{x+2}\right] \) (2) \( \frac{\frac{6 x+5}{x-5}}{\frac{3 x+20}{x-5}+2} \) (3) \( \frac{a^{2}+\left(1-a^{2}\right)}{(1+a) a} \times \frac{(1+a) a}{a^{2}-\left(1-a^{2}\right)} \)

(i) \( 2.25 \% \) of \( x \) is 630
