5 x^{2} - 80 x + 320 = 0

x = 8

Solution steps

5 x^{2} - 80 x + 320 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 80 ) \pm ( - 80 ) ^{2} - 4 \cdot 5 \cdot 320}{2 \cdot 5}

(- 80)^{2} - 4 \cdot 5 \cdot 320 = 0

x_{1, 2} = \frac{- ( - 80 ) \pm 0}{2 \cdot 5}

x = \frac{- ( - 80 )}{2 \cdot 5}

\frac{- ( - 80 )}{2 \cdot 5} = 8

x = 8

The solution to the quadratic equation is:

x = 8

25 = 10 x - x^{2}

- x^{2} + 7 x + 18 = 0

y^{2} + 14 y

7 r^{2} + 84 = - 49 r

y^{2} + 16 y
