Question

plz help me fast with the process and statement plz plz fast​

Answer 1

1) a = mn b = 1

(a+b)^2 = (mn)^2 + 2 × mn×1 + (1)^2

= (mn)^2 +2mn+1

2) a = 6x b =3

(a+b)^2 = (6x)^2 + 2× 6x ×3 + (3)^2

= 36x^2 + 36x + 9

3) a = 4x b= 5y

(a+b)^2 = (4x)^2 + 2×4x×5y +(5y)^2

= 16x^2 + 40xy +25y^2

4) a=pqc b = 2

(a+b)^2 = (pqc)^2 + 2×pqc×2 +(2)^2

= p^2×q^2×c^2 +4pqc+ 4

I hope it help

thank you
