0 = 49 x^{2} - 16

x = \frac{4}{7}, x = - \frac{4}{7}

Decimal Notation

x = 0.57142 \dots, x = - 0.57142 \dots

Solution steps

0 = 49 x^{2} - 16

Switch sides

49 x^{2} - 16 = 0

Move

16

to the right side

49 x^{2} = 16

Divide both sides by

49

x^{2} = \frac{16}{49}

For

x^{2} = f (a)

the solutions are

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

x = \frac{16}{49}, x = - \frac{16}{49}

\frac{16}{49} = \frac{4}{7}

- \frac{16}{49} = - \frac{4}{7}

x = \frac{4}{7}, x = - \frac{4}{7}

7 a^{2} - 300 = 43

5 y^{2} + 26 y = - 5

x^{2} + 28 x + 196 = 0

(x + 4)^{2} - 5 = 31

x^{2} + 4 x - 8 = 0
