u^{2} + 6 u + 9 = 0

u = - 3

Solution steps

u^{2} + 6 u + 9 = 0

Solve with the quadratic formula

u_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 1 \cdot 9}{2 \cdot 1}

6^{2} - 4 \cdot 1 \cdot 9 = 0

u_{1, 2} = \frac{- 6 \pm 0}{2 \cdot 1}

u = \frac{- 6}{2 \cdot 1}

\frac{- 6}{2 \cdot 1} = - 3

u = - 3

The solution to the quadratic equation is:

u = - 3

10 x^{3} - 35 x^{2} - 20 x

6 x^{2} - 180 x + 1296 = 0

7^{\frac{3}{2}}

- \frac{1}{7} x = 3

(7 x + 22)^{2} = 80
