​

Answer 1

Answer:

${x}^{2} + 3x \\ x \times x \times x + 3 \\ x {}^{3} + 3 \\ 4x {}^{3}$

I hope it help you if it correct follow me and like the answer and mark me brainlest

Answer 2

$Given \: polynomial \: x^{2} + 3x$

$i) Coefficient \:of \: x^{3} = 0$

$ii) Coefficient \:of \: x^{2} = 1$

$iii) Coefficient \:of \: x = 3$

Therefore.,

$\red{ Coefficient \:of \: x^{3} \: in \: x^{2} + 3x }$

$\green {= 0}$
