a) \( \frac{1-x}{6 x}+\frac{3-2 x}{2 x^{2}}-\frac{x^{2}+x-4}{3 x^{2}} \)

19. Give the vertex form and factored form of \( f(x)=x^{2}-12 x+35 \). What specific information doe: each form provide?

4. Find the value of the following expressions. Write your answers without any exponents. \( \begin{array}{ll}8^{4}=8^{8-2}=8^{11}= & \text { a) } 7^{7-2}=\end{array} \)

Simplify: \( (3 x+5)^{2} ? \) A \( 9 x^{2}+25 \) B \( 6 x^{2}+10 \) C \( 9 x^{2}+30 x+25 \) D \( 9 x^{2}+15 x+25 \)

The function below has at least one Rational zERO. use this fact to find all zeros of the function \( f(x)=3 x^{3}-2 x^{2}-7 x-2 \) If there is more than zero, seperate them with commas. Write exact values, not decimal approximations.

solve for \( x \) \( \log _{2}(5 x-7)=1 \)
