Solve tan^2 theta + 1 = -2 tan theta on the interval 0° ≤ θ ≤ 360°.

This is my question~~ ( r ^ 4 - 2r ^ 3 - 23 r ^ 2 - 4r - 32)÷(r+4) ~~ i must use long division to solve it : / i was wondering if anyone world like to solve it. and if so, share step-by-step explanations! you! ❤

The difference of three and the reciprocal of a number is equal to the quotient of 20 and the number. find the number.

To convert celsius temperatures to fahrenheit, you can use the expression (c + 32). tom says that another way to write this expression is c + 32. what error did tom make?
