9 u^{2} - 30 u = - 25

u = \frac{5}{3}

Decimal Notation

u = 1.66666 \dots

Solution steps

9 u^{2} - 30 u = - 25

Move

25

to the left side

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

Solve with the quadratic formula

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

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

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

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

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

u = \frac{5}{3}

The solution to the quadratic equation is:

u = \frac{5}{3}

2 x^{2} + 18 x = 7 x + 21

8 x^{2} - 13 x - 6 = 0

x (x + 6) = 216

600 - 200 x + 12 x^{2} = 0

x, x^{2} - 2 x + 184 = 2 x
