Hello,
Please, see the attached file.
Thanks.
Let
. Then differentiating, we get

We approximate
at
with the tangent line,

The
-intercept for this approximation will be our next approximation for the root,

Repeat this process. Approximate
at
.

Then

Once more. Approximate
at
.

Then

Compare this to the actual root of
, which is approximately <u>1.76929</u>2354, matching up to the first 5 digits after the decimal place.
3x - 18 = 42
3x = 42 + 18
3x = 60
x = 60/3
x = 20
(8-7)/(-3-0)= -1/3
the slope is -1/3
