For x<2 \wedge x\not=0 the derivative is negative.
For x>2 the derivative is positive.
Therefore at x=2 there's a minimum.

f_(min)=6\cdot2+(24)/(2^2)+3=12+6+3=21

The easyiest but not the only, way to solve this problem is the FOIL method. You first do a*a=a^2 then a*-2=-2a then a*3=3a then 3*-2=-6 then you add it all together a^2-2a+3a-6 then simplify. so the answer is a^2+a-6! Any more questions?

Can you please solve for m
2 = m/2-7

​

Answers

2 = m/2 - 7                  Original Problem.
m/2 - 7 = 2                  Flip flop the equation around.
m/2 = 9                       Add 7 to each side.
m = 18                        Multiply each side by 2.

Answer: m = 18
