centre = ( - 9, 6)
the equation of a circle in standard form is
(x - a)² + (y - b)² = r²
where (a , b) are the coordinates of the centre and r is the radius
(x + 9)² + (y - 6)² = 102 is in this form
with centre = ( - 9 , 6 )
Might help if you write the equation

No signs of draggin stuff
so PEMDAS
so wha yyou woul ddo first is see if parenthasees can be simplified
it cannot
so next we do multiply or distribute the 9
9(x+2)=9x+18
so now we have
9x+18=90
then we do subtraction
of 18
9x=72
divide 9
x=8
so order is multiplication then subtraction then division
