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

x = \frac{5}{3}, x = - \frac{5}{3}

Decimal Notation

x = 2.88675 \dots, x = - 2.88675 \dots

Solution steps

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

Add similar elements:

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

3 x^{2} = 5^{2}

5^{2} = 25

3 x^{2} = 25

Divide both sides by

3

x^{2} = \frac{25}{3}

For

x^{2} = f (a)

the solutions are

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

x = \frac{25}{3}, x = - \frac{25}{3}

\frac{25}{3} = \frac{5}{3}

- \frac{25}{3} = - \frac{5}{3}

x = \frac{5}{3}, x = - \frac{5}{3}

8 + x < 1

5 m^{2} + 1 = 6

\frac{2116.8}{62.428} - 1.42

x^{2} - 16 x + 100 = 0
