Answer 1

what is (x+a)^2

Answer 2

x^2 + 2ax +a^2

Answer 3

we have x^2 and 2ax terms
just figure out a^2

Answer 4

hint: a is there in 2ax term!!

Answer 5

i think that for (x+a)^2 the a value should be 4a/9? Hence the value for a^2 is 16a/81?

Answer 6

yes
here the value of a is -4a/9 which doesnt alter the value of a^2
cheer up you got the constant term you wanted
