Answer 5

@mathslover help karde yaar

Answer 6

Consider two odd numbers: 2n - 1 and 2n + 1

You've : (2n-1)^2 + (2n+1)^2 = 74

Solve for n ;)

Answer 7

yaara thoda simpply method de

Answer 8

Kaunsi class mein ho tum?

Answer 9

2 saal k baad yeh chapter karaha hu

Answer 10

4n^2 + 1 - 4n + 4n^2 + 1 + 4n = 74

8n^2 + 2 = 74

8n^2 = 72

n^2 = 9

n = +/- 3...
since it is given that odd numbers are positive
so, n = 0

Therefore, numbers : 2n - 1 = 2(3) - 1 = 5 and 2(3) + 1 =7

Answer 11

muhje yeh equation mila
x^2 + 2x - 35 = 0 :/

Answer 12

kar lo toh... use middle term splitting method.

Answer 19

(x-5)(x+7) = 0?
are factor form you have to solve for x

Answer 20

mera step 1 yeh tha
x^2 + (x + 2)^2 = 74

Answer 21

What if x is even?

Answer 22

See, you've to get it generalized. odd number has the form of 2n + 1 where n is any integer.

So, better use : 2n - 1 and 2n + 1 for ease.
