The solutions of the quadratic equation $49x^{2} =9$ are:

$x_{1} = \frac{3}{7}, x_{2} = \frac{-3}{7}$

Step-by-step explanation:

Divide both sides by 49, $\frac{49x^{2} }{49} = \frac{9}{49}$ Simplify $x^{2} = \frac{9}{49}$ For $x^{2} = f(b)$ the solutions are $x = \sqrt{f(b)} , -\sqrt{f(b)}$ So $x_{1} = \frac{\sqrt{9}}{\sqrt{49}}, x_{2} = -\frac{\sqrt{9}}{\sqrt{49}}$ The solutions are: $x_{1} = \frac{3}{7}, x_{2} = -\frac{3}{7}$
