Question

If m=2 and n=1, then find the value polynomial:
$3n-2m^2+3$

• A. $-2$
• B. $-4$
• C. $-10$
• D. None of these

Answer 1

The correct option is A $-2$

Let us substitute $m=2$ and $n=1$ in the given polynomial $3n-2m^2+3$ as shown below:

$3n-2m^2+3=(3\times 1)-2(2{)}^2+3=3-(2\times 4)+3=3-8+3=-8+6=-2$

Hence, $3n-2m^2+3=-2$, if $m=2$ and $n=1$.
