49 x^{2} = 16

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

Solution steps

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}

∣ x + 8 ∣ \leq 3

(4 x - 7) (2 x + 3) - 8 x (x - 4) = 0

x (1 + x) = \frac{3}{4}

(1 - a) + 3 (1 - a)^{2} = 0
