Question

Solve these two questions for me. ​

Answer 1

Answer:

${(3x + 2z)}^{10} \: has \: \: 11 \: \: terms \\ \\ \binom{n}{r} \times {( - 1)}^{r} \times {x}^{r} \: \: \: \\ \: \: \: is \: the \: general \: term \: of \: {(1 - x)}^{n}$

Answer 2

Step-by-step explanation:

$There \: will \: be \: 11 \: terms$

$\boxed{t_{r+1} = ^{n}C_{r} {a}^{n - r} {b}^{r} }\\\\ t_{r+1 }= (-1)^r \ ^{n}C_{r} {1}^{n - r} {x}^{r},\: \:is\:the\: general\:term\:of\:(1-x)ⁿ$
