(a+b)^2=a^2+2ab+b^2

Answer 5

(a-b)^2=a^2-2ab+b^2

Answer 6

Can u show your work not just the formula?

Answer 7

first of all u will take 2 common so it will be :
2 (x-2)+(y+5)=36
then u will divide by 2 : (x-2)+(y+5)=18
then take the brackets out and combine
x-2+y+5=18 ,x+y+3=18 ,move the 3 to da other side
x+y=15 ,y=15-x Or x=15-y
__________
U got it or need more explanation ?
