$f(x) = {x}^{2} - 3x + 2$

<h2>••••••••••••••••••••••••••••••••••••••••</h2>

put x = (-1)

$f( - 1) = {( - 1)}^{2} - 3 \times ( - 1) + 2 \\ \\ 1 + 3 + 2 \\ \\ 6.$

put x = (z)

$f(z) = {z}^{2} - 3 \times z + 2 \\ \\ {z}^{2} - 3z + 2 \\ \\ {z}^{2} - 2z - z + 2 \\ \\ z(z - 2) - 1(z - 2) \\ \\ (z - 1)( z -2 ) \\ \\ (z - 1) = 0 \: \: , \: \: (z - 2) = 0\\ \\ z = 1 \:, \: 2$

I don't know how to simplify this question. Is quotient rule necessary?

barxatty [35]

Answer:

The answer to your question is $\frac{(x+1)^{2}(x - 23)}{(x-7)^{3}}$ , because the directions says to give the answer in factor form.

Step-by-step explanation:

$\frac{3(x+1)^{2}(x-7)^{2}- (x+1)^{3}(2)(x - 7)}{(x - 7)^{4}}$

Factor like terms (x - 7)(x + 1)²

$\frac{(x - 7)(x + 1)^{2}[3(x - 7) - 2(x + 1)}{(x - 7)^{4}}$

Simplify

$\frac{(x+1)^{2}[3(x - 7) - 2(x+1)]}{(x-7)^{3}}$

Expand

$\frac{(x+1)^{2}[3x - 21 -2x - 2]}{(x - 7)^{3}}$

Simplify

$\frac{(x + 1)^{2}(x - 23)}{(x - 7)^{3}}$
