brainly.com/question/10192511Knowing that 1+2i is a root, you also know that 1-2i is a root, so one quadratic factor is
(x -1)² -(2i)² = x^2 -2x +5
Long division of the given polynomial by this quadratic gives a quotient of
x² +9
which has roots ±3i.
Then all
the roots are {-3i, 3i, 1-2i, 1+2i}.
I think it’s 1.75 sorry if this is wrong
-2x + 8 = -4x + 1
- 1 -2x
7 = -6x
—
-6x
7/-6 or -7/6
Answer:
Answer image is attached.
Step-by-step explanation:
Given rational expressions:

And the rewritten forms:

We have to match the rewritten terms with the given expressions.
Let us consider the rewritten terms and let us solve them one by one by taking LCM.

So, correct option is 3.

So, correct option is 1.

So, correct option is 2.

So, correct option is 4.
