Question 120767
Dear student please verify yourself.
Given -9(x-3)^2=7.
This implies that -9(x-3)^2-7=0.
                  -9(x^2+9-6x)-7=0.
                  -9x^2-81+54x-7=0
                  -9x^2+54x-88=0.
Throughout multiply by (-),
                   9x^2-54x+88=0.
Now we use the formula {{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} and simplfy we get the answers  x=3.89 (or) x=2.116
