Solving Quadratics (All Methods)

Solve:
 $f\left(x\right)=x^2+7$   if  $f\left(x\right)=88$  

Solve:
 $f\left(x\right)=x^2-2x-8$  if  $f\left(x\right)=0$  

Solve:
 $f\left(x\right)=2x^2+4x\ \ if\ f\left(x\right)=16$  

SOLVE:
 $f\left(x\right)=\left(5x-4\right)\left(x+3\right)\ \ \ \ if\ \ \ \ f\left(x\right)=0$  

Identify "B" in the quadratic equation:
 $f\left(x\right)=3+8x\ \ \ if\ \ \ f\left(x\right)=4x^2$  

Identify "B" from the quadratic equation: $f\left(x\right)=x^2-7\ \ \ \ \ if\ \ \ \ f\left(x\right)=-6x$
