1.	What should be added or substracted from 9x square or 16y square so as to make a perfect square
Answer» Answer: What should be ADDED to 9x4+2x2+25 to make it a perfect square? We should notice that the polynomial has a positive middle TERM, which IMPLIES that we should end up with (a+b)2 format. 9x4+2x2+25 (3x2)2+(5)2+2x2 We have already made up a2 and b2 , we just need to make the middle term accordingly to TURN it into a perfect square. (3x2)2+2.3x2.5+(5)2−28x2 (3x2+5)2−28x2 Thus, if we add 28x2 to the polynomial, it will turn into a perfect square. Step-by-step explanation: sry if my ANS was wrong

Answer:

What should be ADDED to 9x4+2x2+25 to make it a perfect square?

We should notice that the polynomial has a positive middle TERM, which IMPLIES that we should end up with (a+b)2 format.

9x4+2x2+25

(3x2)2+(5)2+2x2

We have already made up a2 and b2 , we just need to make the middle term accordingly to TURN it into a perfect square.

(3x2)2+2.3x2.5+(5)2−28x2

(3x2+5)2−28x2

Thus, if we add 28x2 to the polynomial, it will turn into a perfect square.
