Question

(m+2n-5p)^2 solve by using identities
​

Answer 1

m^2 +4n^3 +25p^2 +4mn -20np -10mp

( a+b+c )^2 =a^2 +b^2 +c^2 +2ab+2bc+2ac

answer right or wrong write on comment box

Answer 2

Answer:

m^2+4n^2+25p^2+4mn-20np-10mp

Explanation:

(m+2n-5p)^2

identity (a+b+c)^2= a^2+b^2+c^2+2ab+2bc+2ca

m^2+(2n)^2+(-5p)^2+2×m×2n + 2×2n×-5p+2×-5p×m

m^2 + 4n^2+ 25p^2 +4mn-20np-10mp
