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

x = \frac{15 + 145}{2}, x = \frac{15 - 145}{2}

Decimal Notation

x = 13.52079 \dots, x = 1.47920 \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 = 145

x_{1, 2} = \frac{- ( - 15 ) \pm 145}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 15 ) + 145}{2 \cdot 1}, x_{2} = \frac{- ( - 15 ) - 145}{2 \cdot 1}

x = \frac{- ( - 15 ) + 145}{2 \cdot 1} : \frac{15 + 145}{2}

x = \frac{- ( - 15 ) - 145}{2 \cdot 1} : \frac{15 - 145}{2}

The solutions to the quadratic equation are:

x = \frac{15 + 145}{2}, x = \frac{15 - 145}{2}

6 x^{2} + 12 x = 0

x, y (x^{2} + 4) = 10 x

λ^{2} - 6 λ - 16 = 0

x^{2} + 2 x = 25

(x - 9) (x + 8) = 0
