expand (-10000+0.7xcot(y))^2

expand

(- 10000 + 0.7 x cot (y))^{2}

100000000 - 14000 x cot (y) + 0.49 x^{2} cot^{2} (y)

Solution steps

(- 10000 + 0.7 x cot (y))^{2}

Apply Perfect Square Formula:

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

(- 10000 + 0.7 x cot (y))^{2} = (- 10000)^{2} + 2 (- 10000) \cdot 0.7 x cot (y) + (0.7 x cot (y))^{2}

= (- 10000)^{2} + 2 (- 10000) \cdot 0.7 x cot (y) + (0.7 x cot (y))^{2}

Simplify

(- 10000)^{2} + 2 (- 10000) \cdot 0.7 x cot (y) + (0.7 x cot (y))^{2} : 100000000 - 14000 x cot (y) + 0.49 x^{2} cot^{2} (y)

= 100000000 - 14000 x cot (y) + 0.49 x^{2} cot^{2} (y)

2 (x - 2) (x + 13) (x - 13)

\frac{( - 6 + y ^{2} ) ^{2} y}{8}

\frac{x ( x + 1 ) d y}{d x}

\frac{( - \frac{10}{5} x ^{4} y ^{3} z ^{2} )}{( \frac{1}{2} y ^{3} )}

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