Question

subtract : - m2 + mn + n2 from – m2+ mn+ na​

Answer 1

$\sf \: Subtract :- m {}^{2} + mn + n {}^{2} \: from \: - m {}^{2} + mn + na$

Here, we have to do this by the following steps:

$\sf \: - m {}^{2} + mn + na - (m {}^{2} + mn + n {}^{2})$

$\sf \: - m {}^{2} + mn + na - {m}^{2} + mn - n {}^{2}$

$\sf \: - m {}^{2} - {m}^{2} + mn + mn + na - n {}^{2}$

$\sf \: 2 {m}^{2} + 2mn + na - {n}^{2}$

Answer 2

Step-by-step explanation:

\sf \: Subtract :- m {}^{2} + mn + n {}^{2} \: from \: - m {}^{2} + mn + naSubtract:−m2+mn+n2from−m2+mn+na

Here, we have to do this by the following steps:

\sf \: - m {}^{2} + mn + na - (m {}^{2} + mn + n {}^{2})−m2+mn+na−(m2+mn+n2)

\sf \: - m {}^{2} + mn + na - {m}^{2} + mn - n {}^{2}−m2+mn+na−m2+mn−n2

\sf \: - m {}^{2} - {m}^{2} + mn + mn + na - n {}^{2}−m2−m2+mn+mn+na−n2

\sf \: 2 {m}^{2} + 2mn + na - {n}^{2}2m2+2mn+na−n2
