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+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+ and simplfy we get the answers x=3.89 (or) x=2.116
