Question

for a=3 and b=4 verify the identies (a+b2=a2+2ab+b2 and a2-b2=(a+b) (a-b)
​

Answer 1

Answer:

Step-by-step explanation:

a=3 and b=4

Tp:(a+b)^2=a^2+b^2+2ab

Proof: putting values of a and b

(3+4)^2=3^2+4^2+2(3*4)

7^2=9+16+2(12)

49=25+24

49=49

As lhs =rhs

Hence proved similarly for the other one.
