D in (-00+00)
(3/8)*d-(3/4)=0
(3/8)*d-3/4=0
3/8*d-3/4=0 // + 3/4
3/8*d= 3/4 // : 3/8
d = 3/4/3/4
d=2
d=2

The coefficient of the variable is 3/8.

$\sf\dfrac{3}{8}(?+?)$

Divide 3/8 to each term to find out what goes in the parenthesis:

$\sf\dfrac{3}{8}b\div\dfrac{3}{8}=b$

So 'b' goes into the first spot in the parenthesis:

$\sf\dfrac{3}{8}(b+?)$

$\sf\dfrac{3}{4}\div\dfrac{3}{8}$

When dividing by fractions we flip(reciprocal) the one we're dividing by and multiply:

$\sf\dfrac{3}{4}\times\dfrac{8}{3}$

Multiply:

$\sf\dfrac{24}{12}$

Divide:

$\sf 2$

This goes into the second spot in our parenthesis.

$\boxed{\sf\dfrac{3}{8}(b+2)}$

Find the taylor series for f(x) centered at the given value of a. [assume that f has a power series expansion. do not show that

Bond [772]

Taylor series is $f(x) = ln2 + \sum_{n=1)^{\infty}(-1)^{n-1} \frac{(n-1)!}{n!(9)^{n}(x9)^{2} }$

To find the Taylor series for f(x) = ln(x) centering at 9, we need to observe the pattern for the first four derivatives of f(x). From there, we can create a general equation for f(n). Starting with f(x), we have

f(x) = ln(x)

$f^{1}(x)= \frac{1}{x} \\f^{2}(x)= -\frac{1}{x^{2} }\\f^{3}(x)= -\frac{2}{x^{3} }\\f^{4}(x)= \frac{-6}{x^{4} }$
