4 x^{2} - x - 9 = - x - 8

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

Decimal Notation

x = 0.5, x = - 0.5

Solution steps

4 x^{2} - x - 9 = - x - 8

Move

9

to the right side

4 x^{2} - x = - x + 1

Move

x

to the left side

4 x^{2} = 1

Divide both sides by

4

x^{2} = \frac{1}{4}

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

x = \frac{1}{4}, x = - \frac{1}{4}

\frac{1}{4} = \frac{1}{2}

- \frac{1}{4} = - \frac{1}{2}

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

- 0.0006 t^{2} + 0.048 t - 0.29 = 0

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

2 (x^{2} + 2 x + 1) + 4 x = - (x - 1)^{2}

36.6 = - 2 \cdot 1 0^{- 5} x^{2} - 0.1313 x + 233.04

- 5 x^{2} = - 80
