to the left side

9 z^{2} - 30 z + 25 = 0

Solve with the quadratic formula

z_{1, 2} = \frac{- ( - 30 ) \pm ( - 30 ) ^{2} - 4 \cdot 9 \cdot 25}{2 \cdot 9}

(- 30)^{2} - 4 \cdot 9 \cdot 25 = 0

z_{1, 2} = \frac{- ( - 30 ) \pm 0}{2 \cdot 9}

z = \frac{- ( - 30 )}{2 \cdot 9}

\frac{- ( - 30 )}{2 \cdot 9} = \frac{5}{3}

z = \frac{5}{3}

The solution to the quadratic equation is:

z = \frac{5}{3}

∣ w + 2 ∣ - ∣ w - 2 ∣ = 2 w

5.3 x^{2} - 17 x + 10 = 0

∣ 7 x + 2 ∣ > 2

(\frac{2 x ^{3}}{y ^{2}})^{4}
