expand (6cot(θ)+5)^2

expand

(6 cot (θ) + 5)^{2}

36 cot^{2} (θ) + 60 cot (θ) + 25

Solution steps

(6 cot (θ) + 5)^{2}

Apply Perfect Square Formula:

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

(6 cot (θ) + 5)^{2} = (6 cot (θ))^{2} + 2 \cdot 6 cot (θ) \cdot 5 + 5^{2}

= (6 cot (θ))^{2} + 2 \cdot 6 cot (θ) \cdot 5 + 5^{2}

Simplify

(6 cot (θ))^{2} + 2 \cdot 6 cot (θ) \cdot 5 + 5^{2} : 36 cot^{2} (θ) + 60 cot (θ) + 25

= 36 cot^{2} (θ) + 60 cot (θ) + 25

4 (72 x^{7} ln (x) + 17 x^{7}) x^{2}

(- 7 d^{2} + 4 e - 6 f^{3}) (d^{2} + 3 e + 3 f^{3})

- 4 (5 - x = - 16)

\frac{d}{d t} ((x) (t^{2} + 5))

(5 sin (θ) + 2)^{2}
