x^{2} - x = - 0.25

x = \frac{1}{2}

Decimal Notation

x = 0.5

Solution steps

x^{2} - x = - 0.25

Multiply both sides by

100

x^{2} \cdot 100 - x \cdot 100 = - 25

Move

25

to the left side

x^{2} \cdot 100 - x \cdot 100 + 25 = 0

Write in the standard form

a x^{2} + b x + c = 0

100 x^{2} - 100 x + 25 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 100 ) \pm ( - 100 ) ^{2} - 4 \cdot 100 \cdot 25}{2 \cdot 100}

(- 100)^{2} - 4 \cdot 100 \cdot 25 = 0

x_{1, 2} = \frac{- ( - 100 ) \pm 0}{2 \cdot 100}

x = \frac{- ( - 100 )}{2 \cdot 100}

\frac{- ( - 100 )}{2 \cdot 100} = \frac{1}{2}

x = \frac{1}{2}

The solution to the quadratic equation is:

x = \frac{1}{2}

s^{2} = 5

- 4.9 x^{2} + 33 x = 0

15 x^{2} - 10 x = 0

2 x^{2} - 3 x - 8 = 0

3 x (x - 8) = 0
