Simplify the expression $\frac {4x-8}{x^{2}-4}/\frac {4}{-2x-4}$ $\square $
Simplify: $(7+2\sqrt {3})^{2}$ $\square $
Write the sum using summation notation. There may be multiple representations. Use i as the index of summation. $-\frac {1}{4}+\frac {1}{16}-\frac {1}{64}+\frac {1}{256}-\frac {1}{1024}$ We can write the sum as $\sum _{i=1}^{5}\square $
(1 point)Divide $x^{5}-3x^{4}-23x^{3}+51x^{2}+94x-120b$ $x^{2}-4x+3$ Answer: $\square x^{3}+\square x^{2}+\square x+$ $\square $
Solve the inequality: $n^{2}\gt 7n+30$ Give your answer in interval notation. Enter DNE if there is no solution. $\square $
Find the derivative of: $h(x)=\frac {x^{3}+3x+4}{x^{3}+3x-2}$
Factor the following polynomial. $91x^{2}+8x-3$
Solve. $\frac {x}{x-1}-\frac {5}{x+1}=\frac {2}{x^{2}-1}$ $x=\square $ (Simplify your answer.including any radicals and i as needed. Use integers or fractions for any numbers in the expression. Use a comma to separate answers as needed.)
Use the quotient rule to simplify. Assume that all variables represent positive real numbers. $\sqrt [4]{\frac {13x}{243y^{16}}}$
Rotating an object 360 degrees counterclockwise gets the same result as rotating the object __ degrees clockwise. $\square $
