Question 322121
review explaination below
w=-0,12

{{{-6(12)^2+72(12)}}}
{{{-6(144)+864}}}
{{{-864+864}}}
{{{0}}}
{{{A=-6w^2+72w}}} thruogh guess and check doing the quadratic formula several times with different amouts i came to find the following:
if A=217 then it is an imaginary answer so A has to equal 216 as its maximum
216=-6w^2+72w
0=-6w^2+72w-216
W=6
*[invoke quadratic "w", -6, 72, 0]
