x^{2} + 10 x + 5 = 30

x = 5 (2 - 1), x = - 5 (1 + 2)

Decimal Notation

x = 2.07106 \dots, x = - 12.07106 \dots

Solution steps

x^{2} + 10 x + 5 = 30

Move

30

to the left side

x^{2} + 10 x - 25 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 1 \cdot ( - 25 )}{2 \cdot 1}

1 0^{2} - 4 \cdot 1 \cdot (- 25) = 102

x_{1, 2} = \frac{- 10 \pm 10 2}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 10 + 10 2}{2 \cdot 1}, x_{2} = \frac{- 10 - 10 2}{2 \cdot 1}

x = \frac{- 10 + 10 2}{2 \cdot 1} : 5 (2 - 1)

x = \frac{- 10 - 10 2}{2 \cdot 1} : - 5 (1 + 2)

The solutions to the quadratic equation are:

x = 5 (2 - 1), x = - 5 (1 + 2)

y, x^{3} + y^{2} = 2 x y^{2}

x (x - 9) = 2 + (2 x + 1) (x - 4)

x^{2} - 2 x - 7.88 = 0

x, x^{2} y + y^{2} = 10

3 x^{2} + 9 x - 120 = 0
