x^{2} - 18 x - 77 = 0

x = 9 + 158, x = 9 - 158

Decimal Notation

x = 21.56980 \dots, x = - 3.56980 \dots

Solution steps

x^{2} - 18 x - 77 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 18 ) \pm ( - 18 ) ^{2} - 4 \cdot 1 \cdot ( - 77 )}{2 \cdot 1}

(- 18)^{2} - 4 \cdot 1 \cdot (- 77) = 2158

x_{1, 2} = \frac{- ( - 18 ) \pm 2 158}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 18 ) + 2 158}{2 \cdot 1}, x_{2} = \frac{- ( - 18 ) - 2 158}{2 \cdot 1}

x = \frac{- ( - 18 ) + 2 158}{2 \cdot 1} : 9 + 158

x = \frac{- ( - 18 ) - 2 158}{2 \cdot 1} : 9 - 158

The solutions to the quadratic equation are:

x = 9 + 158, x = 9 - 158

4 t (3 - t) = 4 t + 3

(a + c) (a - c) = 0

x, ((p - 3) (p + 5)) \cdot x^{2} - 4 x + 8 = 0

x lo g_{10} (10) (x - 3) = 2

x, 2 x^{2} - 4 x y + 2 y^{2} - 5 x - 5 = 0
