49 x^{2} - 16 = 20

x = \frac{6}{7}, x = - \frac{6}{7}

Decimal Notation

x = 0.85714 \dots, x = - 0.85714 \dots

Solution steps

49 x^{2} - 16 = 20

Move

16

to the right side

49 x^{2} = 36

Divide both sides by

49

x^{2} = \frac{36}{49}

For

x^{2} = f (a)

the solutions are

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

x = \frac{36}{49}, x = - \frac{36}{49}

\frac{36}{49} = \frac{6}{7}

- \frac{36}{49} = - \frac{6}{7}

x = \frac{6}{7}, x = - \frac{6}{7}

42 x^{2} = - 287 x + 392

3 x^{2} = x - 9

d, a = \frac{1}{2} d^{2}

2 x^{2} + 26 = - 10

a, z = \neg (a \land \neg b) \lor (\neg a \land b)
