Question

Find the coefficient of x in the expansion of (x + 3)”.​

Answer 1

Step-by-step explanation:

$\huge\fbox\pink{A}\fbox\blue{n}\fbox\purple{S}\fbox\green{w}\fbox\red{E}\fbox\orange{r}$

${\bold{\sf{(x + 3)³ = x3 + 33 + 3x (3)(x + 3)}}}$

${\bold{\sf{\red{➝ \: Using \: Identity, (a + b)³ = a³ + b³ + 3ab (a + b)}}}}$

${\bold{\sf{x³ + 27 + 9x (x + 3)}}}$

${\bold{\sf{x³ +27 + 9x²+27x}}}$

${\large{\sf{\orange{Hence, \: the \: coefficient \: of \: x \: in (x + 3)³ \: is \: 27}}}}$

Answer 2

Answer:

Polynomial-- x+3

Coefficient of x is 1

So,1 is ur @n$wer..
