Ans:
Hello Student,
Please find answer to your question below

It can be done by many analytical methods.
Lets start with
$-20 = -20$
$16-36 = 25-45$
$(2+2)^{2}-(2+2).9 = (5)^{2}-5.9$
$(2+2)^{2}-2.(2+2).\frac{9}{2} = (5)^{2}-2.5.\frac{9}{2}$
$(2+2)^{2}-2.(2+2).\frac{9}{2} + (\frac{9}{2})^{2} = (5)^{2}-2.5.\frac{9}{2}+(\frac{9}{2})^{2}$
$(2+2-\frac{9}{2})^{2} = (5-\frac{9}{2})^{2}$
$2+2-\frac{9}{2}= 5-\frac{9}{2}$
$2+2= 5$
Hence, Proved.
