expand ((-21)/(34)-(16x)/(-17))^2

expand

(\frac{- 21}{34} - \frac{16 x}{- 17})^{2}

\frac{441 - 1344 x + 1024 x ^{2}}{1156}

Solution steps

(\frac{- 21}{34} - \frac{16 x}{- 17})^{2}

Apply Perfect Square Formula:

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

(\frac{- 21}{34} - \frac{16 x}{- 17})^{2} = (\frac{- 21}{34})^{2} - 2 \cdot \frac{- 21}{34} \cdot \frac{16 x}{- 17} + (\frac{16 x}{- 17})^{2}

= (\frac{- 21}{34})^{2} - 2 \cdot \frac{- 21}{34} \cdot \frac{16 x}{- 17} + (\frac{16 x}{- 17})^{2}

Simplify

(\frac{- 21}{34})^{2} - 2 \cdot \frac{- 21}{34} \cdot \frac{16 x}{- 17} + (\frac{16 x}{- 17})^{2} : \frac{441 - 1344 x + 1024 x ^{2}}{1156}

= \frac{441 - 1344 x + 1024 x ^{2}}{1156}

(x^{2} + x + 1) (- 15 x^{2} + 15 x - \frac{3}{2})

11 z (- z + 11)

(- \frac{2}{9} x - \frac{1}{3}) (2 x - 3)

\frac{x + 16}{x ^{2} ( x ^{2} + 4 )}
