So I found the derivative of an expression and I cannot figure out how to simplify the final answer into the desired form. I got -csc^2(X)/(1+cotx)^2. Now how do I simplify this into -1/(sinx+cosx)^2. Help, it's killing me ahha. Thanks!

Can someone help me with this problem please? rationalize the denominator and simlify the answer: 5/2 + the square root of 3 Do you mean 5/(2 + sqrt 3) ? What you wrote could also be interpreted as 2.5 + sqrt 3. You need to be more careful to use

92. ## Math- Completely confused!

Simplify each expression (where possible) and write the answer without using negative or fractional exponents. Assume that X>0. a. 8x^(1/3) b. (-8x)^(1/3) c. (8x)^(-1/3) d. (3x^(3/4))(16x)^(1/4) e. (x^(1/2)) / (x^(5/2) so far my answers are : a.2x b. -2x

Simplify [(1)-(1/x+2)] / [(1)- (3/x+4)] I know I need to find the LMC here, and the answer is (x+4)/(x+2) but I do not know how to get to the answer and how to use the LMC. I need help! You need to use more parentheses to distiguish (1/x)+ 2 from 1/(x+2),

Resolve(17x²+14x + 9) – (-13x² +6x - 12) 30xsquared+20x+21 I'll try to be helpful and show the work. This is the method I learned last quarter. (17x"sq"+14x+9) + (13x"sq"+6x+12) = (30X"sq"+20x+21) I used the vertical method but the step are the same
