x^{2} + 5 x - 90 = 0

x = \frac{- 5 + 385}{2}, x = \frac{- 5 - 385}{2}

Decimal Notation

x = 7.31070 \dots, x = - 12.31070 \dots

Solution steps

x^{2} + 5 x - 90 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 \cdot 1 \cdot ( - 90 )}{2 \cdot 1}

5^{2} - 4 \cdot 1 \cdot (- 90) = 385

x_{1, 2} = \frac{- 5 \pm 385}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 5 + 385}{2 \cdot 1}, x_{2} = \frac{- 5 - 385}{2 \cdot 1}

x = \frac{- 5 + 385}{2 \cdot 1} : \frac{- 5 + 385}{2}

x = \frac{- 5 - 385}{2 \cdot 1} : \frac{- 5 - 385}{2}

The solutions to the quadratic equation are:

x = \frac{- 5 + 385}{2}, x = \frac{- 5 - 385}{2}

\frac{1}{90} e^{\frac{1}{90}}

35 - 21 d + 3 d t - 5 t

(0.02)^{2}

x^{2} - 4 x - 7 = 1

(x - 3)^{2} - 20 = 0
