x^{2} - 14 x - 11 = - 30

x = 7 + 30, x = 7 - 30

Decimal Notation

x = 12.47722 \dots, x = 1.52277 \dots

Solution steps

x^{2} - 14 x - 11 = - 30

Move

30

to the left side

x^{2} - 14 x + 19 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 14 ) \pm ( - 14 ) ^{2} - 4 \cdot 1 \cdot 19}{2 \cdot 1}

(- 14)^{2} - 4 \cdot 1 \cdot 19 = 230

x_{1, 2} = \frac{- ( - 14 ) \pm 2 30}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 14 ) + 2 30}{2 \cdot 1}, x_{2} = \frac{- ( - 14 ) - 2 30}{2 \cdot 1}

x = \frac{- ( - 14 ) + 2 30}{2 \cdot 1} : 7 + 30

x = \frac{- ( - 14 ) - 2 30}{2 \cdot 1} : 7 - 30

The solutions to the quadratic equation are:

x = 7 + 30, x = 7 - 30

(x + 1)^{2} - 1 \frac{1}{3} = 0

x, (x + 8)^{2} = 16

y, y^{2} + x^{2} = 0

x^{2} - 6 x - 33 = - 4 x + 2

8 p^{2} + 8 p - 5 = 0
