simplify

\frac{1}{x ^{2}} + \frac{1}{y ^{2}}

\frac{y ^{2} + x ^{2}}{x ^{2} y ^{2}}

Solution steps

\frac{1}{x ^{2}} + \frac{1}{y ^{2}}

Least Common Multiplier of

x^{2}, y^{2} : x^{2} y^{2}

Adjust Fractions based on the LCM

= \frac{y ^{2}}{x ^{2} y ^{2}} + \frac{x ^{2}}{x ^{2} y ^{2}}

Apply the fraction rule:

\frac{a}{c} + \frac{b}{c} = \frac{a + b}{c}

= \frac{y ^{2} + x ^{2}}{x ^{2} y ^{2}}

9 (13 - x) - 4 x = 5 (21 - 2 x) + 9 x

4 - \frac{1}{8}

9 + \frac{x}{3} \geq 4 - \frac{x}{2}

9^{\frac{- 5}{2}}

∣ x - 7 ∣ \geq 6
