Factor the polynomial: \( 2 x^{2}(x-5)-3(x-5) \) \( \begin{array}{l}\text { A. }(x-5)(2 x-3) \\ \text { B. }(x-5)\left(2 x^{2}-3\right) \\ \text { C. }(x-5)\left(2 x^{2}+3\right) \\ \text { D. } 2 x^{2}(x-5)\end{array} \)

\( x=3f(x)=\frac{1}{2}x^{2}-\frac{1}{2} \)

av \( x>0, A=\sqrt{25 x^{2}}-\sqrt{4 x^{2}}-x \)

b. read none of magazine at all c. read exactly one of the magazines. 3. Use Mathematical induction to prove that \( x^{n}+y^{n} \) is divisible by \( x+y \) for odd natural number \( n \geq 1 \). 4. Solve the equation \( z^{6}+1=\sqrt{3} i \) where \( z \in c \).

2. Find the value of \( x \) if \( 9^{x+1}=27 \)

Perform the indicated operations, then simplify. \( \frac{5 y}{y+6}+\frac{7 y^{2}}{y^{2}-36}-\frac{4}{y-6} \) \( \frac{7 y^{2}+5 y-4}{y^{2}+2 y-36} \) \( \frac{12 y^{2}-34 y-24}{(y+6)(y-6)} \) \( \frac{12 y^{2}-34 y+24}{(y-6)(y+6)} \) \( \frac{7 y^{2}+5 y-4}{(y+6)(y-6)} \)
