I have been sitting at this function for a couple of hours, trying to solve it.
0.1w^2 + 2155w + 20
I am kind of dumbfounded by this. Even if I factor out the 0.1, I cannot figure this out.
Appreciate your help,
well you can set it up using dwsmith's method, which applies the "abc robot"
but the expression must be equal to zero to use that.
Multiplying zero by anything is zero, so multiply by 10 for convenience
Multiply both sides by 10.
Take square roots and finally subtract 10775 from both sides.
