Evaluate :$(m+3) (m-5)$
Given :
The given expression is $(m+3)(m-5)$
To find :
We have to evaluate the given term.
Solution :
We know that,
$(a+b) \times (c+d) = a\times(c+d) + b \times (c+d)$
Therefore,
$(m+3)(m-5) = m(m-5)+3(m-5)$
$= m(m)-m(5)+3(m)-3(5)$
$=m^2-5m+3m-15$
$=m^2-2m-15$.
$(m+3)(m-5) =m^2-2m-15$.
 Therefore, after evaluation of the expression $(m+3)(m-5)$ we get $m^2-2m-15$.
