1.2$z^{2}$ - 7 = -34 Add 7 to both sides. 1.2$z^{2}$ - 7 + 7 = -34 + 7 1.2$z^{2}$ = -27 Divide both sides by 1.2: 1.2$z^{2}$ = -27 $\frac{1.2z^{2}}{1.2}$ = $\frac{-27}{1.2}$ $z^{2}$ = -22.5 Normally, we would now take the square root of $z^{2}$ and -22.5. We cannot take the square root of a negative number, however, so there is no solution to this equation.
