x^{2} - \frac{1}{2} x - \frac{1}{2} = 0

x = 1, x = - \frac{1}{2}

Decimal Notation

x = 1, x = - 0.5

Solution steps

x^{2} - \frac{1}{2} x - \frac{1}{2} = 0

Multiply both sides by

2

2 x^{2} - x - 1 = 0

Solve with the quadratic formula

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

(- 1)^{2} - 4 \cdot 2 (- 1) = 3

x_{1, 2} = \frac{- ( - 1 ) \pm 3}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- ( - 1 ) + 3}{2 \cdot 2}, x_{2} = \frac{- ( - 1 ) - 3}{2 \cdot 2}

x = \frac{- ( - 1 ) + 3}{2 \cdot 2} : 1

x = \frac{- ( - 1 ) - 3}{2 \cdot 2} : - \frac{1}{2}

The solutions to the quadratic equation are:

x = 1, x = - \frac{1}{2}

y^{2} - 4 y - 21 = 0

a, a^{2} w^{2} - 16 = 0

4 x^{2} - 16 x + 25 = 0

x^{2} - 15 x + 56.25 = 8

x^{2} + \frac{x}{3} = \frac{2}{3}
