Question

Find the missing terms in the following questions
i) (Y+5)²=y²+10y+…………..
ii) (2y+3)²=4y²+……+9
iii) (3y+…….)²=9y²+24y+……
iv) If we added or substrate an natural number from 12²+5²,we will get a perfect square. Which is the natural number ?​

Answer 1

Given:

We have following questions

i) (y+5)²=y²+10y+…………..

ii) (2y+3)²=4y²+……+9

iii) (3y+…….)²=9y²+24y+……

To Find:

Blanked place digits or number?

Step-by-step explanation:

We can solve it by using formula of whole square of two terms

          $(a+b)^2=a^2+b^2+2ab$

1) (y+5)²=y²+10y+25

2)(2y+3)²=4y²+12y+9

3) (3y+4)²=9y²+24y+16
