x (x - 11) + 30 = 0

x = 6, x = 5

Solution steps

x (x - 11) + 30 = 0

Expand

x (x - 11) + 30 : x^{2} - 11 x + 30

x^{2} - 11 x + 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 11 ) \pm ( - 11 ) ^{2} - 4 \cdot 1 \cdot 30}{2 \cdot 1}

(- 11)^{2} - 4 \cdot 1 \cdot 30 = 1

x_{1, 2} = \frac{- ( - 11 ) \pm 1}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 11 ) + 1}{2 \cdot 1}, x_{2} = \frac{- ( - 11 ) - 1}{2 \cdot 1}

x = \frac{- ( - 11 ) + 1}{2 \cdot 1} : 6

x = \frac{- ( - 11 ) - 1}{2 \cdot 1} : 5

The solutions to the quadratic equation are:

x = 6, x = 5

2 n^{2} - 19 n + 17 = - 3 n^{2}

9 x^{2} + 18 x - 68 = 7

3 x^{2} - 2 x + 4 = 0

(5 m + 1)^{2} = 7

2 x^{2} + 4 x + 2 = 0
