1 - 4 x^{2} = - 8

x = \frac{3}{2}, x = - \frac{3}{2}

Decimal Notation

x = 1.5, x = - 1.5

Solution steps

1 - 4 x^{2} = - 8

Move

1

to the right side

- 4 x^{2} = - 9

Divide both sides by

- 4

x^{2} = \frac{9}{4}

For

x^{2} = f (a)

the solutions are

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

x = \frac{9}{4}, x = - \frac{9}{4}

\frac{9}{4} = \frac{3}{2}

- \frac{9}{4} = - \frac{3}{2}

x = \frac{3}{2}, x = - \frac{3}{2}

21 - 6 x^{2} = 11 x

100 + 50 x - 4.9 x^{2} = 0

- 5 t^{2} + (20 + 6 e^{- 4}) t - (16 + 15 e^{- 4}) = 0

x^{2} - \frac{3}{4} x - \frac{7}{64} = 0

A^{2} = A
