1. 1
Solve by factoring. $$3x^2+4x-15=0$$
2. 2
Solve by factoring. $$6x^2=3-7x$$
3. 3
Solve. Show exact and approximate answers to two decimal places.
$$4x^2-12x+7=0$$

When you can't factor easily use the quadratic formula: $$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$$
4. 4
Solve. ( answer in the form a+bi ) ($x \in C$). $$x^2+2x+2=0$$
5. 5
Solve. Show exact and approximate answers to two decimal places. $$3x^2-2=-6x$$
6. 6
Solve. ( answer in the form a+bi ) ($x \in C$). $$x^2-4x+12=0$$

Good test question !
