Differentiate 2x^3+23x^2+3x+5 and find the values of x for which the function f(x) is at either at a maximum or minimum point. (Don't need to specify which is which)

f(x)=2x 3 +23x 2 +3x+5 f'(x)=6x 2 +46x+3 Maximum or minimum when f'(x)=0 6x 2 +46x+3=0 Using the Quadratic Formula: x=(-b+-squareroot(b 2 -4ac))/2a x 1 =-0.0658 x 2 =-7.6
