Answer

$x=\frac{1}{2}$ and $x=8$

Work Step by Step

Subtract $34x$ from each side: \begin{align*} 4x^2+16-34x&=34x-34x\\ 4x^2-34x+16&=0 \end{align*} Factor out $2$: \begin{align*} 2(2x^2-17x+8)&=0 \end{align*} Factor the trinomial: \begin{align*} 2(2x-1)(x-8)&=0 \end{align*} Use the Zero-Product Property by equating each factor with a variable to zero, then solve each equation: \begin{align*} 2x-1&=0 &\text{or}& &x-8=0\\\\ 2x&=1 &\text{or}& &x=8\\\\ x&=\frac{1}{2} &\text{or}& &x=8 \end{align*}
