make sure you copy the problem properly next time, either use ^2 to indicate squared or even better read how to write formulas here like so -9%28x-3%29%5E2=-7%29%29%29%0D%0Adivide+each+side+by+-9%0D%0A%7B%7B%7B%28x-3%29%5E2=7%2F9 next take a square root of each side
case 1:
x-3=sqrt%287%29%2F3 add 3 to each side
x=%28sqrt%287%29%2B9%29%2F3
case 2:
x-3=-sqrt%287%29%2F3 add 3 to each side
x=%28-sqrt%287%29%2B9%29%2F3
