Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

(13 + 6)^{2} = (13)^{2} + 213 \cdot 6 + 6^{2}

= (13)^{2} + 213 \cdot 6 + 6^{2}

(13)^{2} + 213 \cdot 6 + 6^{2} = 49 + 1213

= 49 + 1213

\frac{3}{4} + \frac{5}{8} - \frac{7}{12}

(- 7 + 7 i) (- 10 - 9 i)

\frac{6}{15} = 2 - \frac{x}{5}

\frac{4}{7} x - 4 > 8

4 = \frac{2}{3} x + 9 + \frac{1}{3} x
