121 = 64 x^{2}

x = \frac{11}{8}, x = - \frac{11}{8}

Decimal Notation

x = 1.375, x = - 1.375

Solution steps

121 = 64 x^{2}

Switch sides

64 x^{2} = 121

Divide both sides by

64

x^{2} = \frac{121}{64}

For

x^{2} = f (a)

the solutions are

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

x = \frac{121}{64}, x = - \frac{121}{64}

\frac{121}{64} = \frac{11}{8}

- \frac{121}{64} = - \frac{11}{8}

x = \frac{11}{8}, x = - \frac{11}{8}

4 y^{2} = 16 y + 3

6 - 2 x - x^{2} = x + 6

2 x^{2} - 4 < 0

x^{2} + 4 x = - 5

9 e = 45
