Answer 1

$\large\star\boxed{\sf{\green{GIVEN:-}}}$

$x + 4 \\ \: is \: the \: factor \: of \: polymonial \: \\ {x}^{2} + 3x + m$

$\large\star\boxed{\sf{\green{SOLUTION:-}}}$

$x + 4$

SO,

$x = - 4$

AS X+4 IS THE FACTOR OF THE POLYNOMIAL

So,

${( - 4)}^{2} + 3 \times( - 4 ) + m = 0$

$8 + ( - 12) + m = 0$

$8 - 12 + m = 0$

$- 4 + m = 0$

$therefore \: m = 4$

SO YOUR ANSWER WILL BE (i)

$4$
