1-104.

Solve each equation. Give solutions in both exact and approximate forms.

1. $x^2 + 3x - 3 = 0$

This equation cannot be factored.

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{-3\pm\sqrt{21}}{2}$

$x\approx-3.79\text{ or }x\approx0.79$

1. $3x^2 - 7x = 12$

First, put the equation in Standard Form: $ax^2 + bx + c = 0$

See part (a).
