if im reading this correctly, youre multiplying (x+10) by -5 and 2, so distribute the numbers so you get -10x-100 and then add 100 to both sides and divide both sides by -10 to get your answer
Reiny
again, I think they mean
-5(x + 10)^2=390,625
(why would you put a multiplier in front and behind a binomial ?)
(x+10)^2 = -78125
which is not possible since the square of anything is positive.
So, no solution.
