Find the product (3 cot y+1)(cot y -2)

Answer 1

Using the distributive property, we can expand the expression:

(3 cot y + 1)(cot y - 2)

= 3 cot y * cot y + 3 cot y * (-2) + 1 * cot y + 1 * (-2)

= 3 cot^2(y) - 6 cot y + cot y - 2

= 3 cot^2(y) - 5 cot y - 2

So, the product of (3 cot y + 1)(cot y - 2) is 3 cot^2(y) - 5 cot y - 2.
