Answer 1

$\mathtt{\huge{\underline{SOLUTION:-}}}$


Question:-

Find the value of the following expressions if m=2,n=-1,a=3m and b=5n:


m2+3mn-n (Equation-1)

Method of Solution:-

Substitute the Value of Required terms in Equation 1


m²+3mn-n

where;

m=2

n=-1

a=3m

b=5n

Now,

Substitute the value;

m²+3mn-n

(2)²+3.2.-1-(-1)

=> 4+6×-1 +1

=> 4-6+1

=> 4+1-6

=> 5-6

=-1
