x^{2} - 15 x - 20 = 0

x = \frac{15 + 305}{2}, x = \frac{15 - 305}{2}

Decimal Notation

x = 16.23212 \dots, x = - 1.23212 \dots

Solution steps

x^{2} - 15 x - 20 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 15 ) \pm ( - 15 ) ^{2} - 4 \cdot 1 \cdot ( - 20 )}{2 \cdot 1}

(- 15)^{2} - 4 \cdot 1 \cdot (- 20) = 305

x_{1, 2} = \frac{- ( - 15 ) \pm 305}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 15 ) + 305}{2 \cdot 1}, x_{2} = \frac{- ( - 15 ) - 305}{2 \cdot 1}

x = \frac{- ( - 15 ) + 305}{2 \cdot 1} : \frac{15 + 305}{2}

x = \frac{- ( - 15 ) - 305}{2 \cdot 1} : \frac{15 - 305}{2}

The solutions to the quadratic equation are:

x = \frac{15 + 305}{2}, x = \frac{15 - 305}{2}

x^{2} - 6 = 43

g, 3 = N g^{2} - Q

t^{2} + 5 t - 6 = 0

6 x^{2} + 96 x + 378 = 0

t^{2} + 4 = 0
