x^{2} = 0.49

x = \frac{7}{10}, x = - \frac{7}{10}

Decimal Notation

x = 0.7, x = - 0.7

Solution steps

x^{2} = 0.49

For

x^{2} = f (a)

the solutions are

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

x = 0.49, x = - 0.49

0.49 = \frac{7}{10}

- 0.49 = - \frac{7}{10}

x = \frac{7}{10}, x = - \frac{7}{10}

(2 x + 5)^{2} - 33 = - 8

x (2 x + 1) = 1

a^{2} + 76 a + 72 = 0

- 2 x^{2} + 20 x = 0

x^{2} - 2 x - 5 = x + 5
