#color(red)(A=35)#

Explanation:

#2^2-1-9*2^2-2+1A=0#

Rearranging the equation by combining the like terms :
#(2^2-9*2^2)-1-2+1A=0#
#2^2(1-9)-(1+2)+1A = 0#

#4*(-8)-3+1A = 0 color(white)(aaa)#writing #2^2 ascolor(white)(a)4#
#-32-3+A=0# as #**1A=A**#

#A=32+3=35color(white)(aaa)# taking constant terms to R H S.
