x^{2} + 15 x - 30 = 0

x = \frac{- 15 + 345}{2}, x = \frac{- 15 - 345}{2}

Decimal Notation

x = 1.78708 \dots, x = - 16.78708 \dots

Solution steps

x^{2} + 15 x - 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 15 \pm 1 5 ^{2} - 4 \cdot 1 \cdot ( - 30 )}{2 \cdot 1}

1 5^{2} - 4 \cdot 1 \cdot (- 30) = 345

x_{1, 2} = \frac{- 15 \pm 345}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 15 + 345}{2 \cdot 1}, x_{2} = \frac{- 15 - 345}{2 \cdot 1}

x = \frac{- 15 + 345}{2 \cdot 1} : \frac{- 15 + 345}{2}

x = \frac{- 15 - 345}{2 \cdot 1} : \frac{- 15 - 345}{2}

The solutions to the quadratic equation are:

x = \frac{- 15 + 345}{2}, x = \frac{- 15 - 345}{2}

x^{2} - 3 (2 x - 5) = 10

x (2 - x) = - 2

x, x^{2} - k x + 1681 = 0

(2 x - 1)^{2} = (x + 1)^{2}

(x - 9)^{2} = - 36
