Which of the following is the reciprocal of x2 – 2x – 8?

Ann [662]

Hi again

x² - 2x - 8
Factor
= (x + 2)(x -4)
Answer : A is the correct option.

If you wanna check if A is the right answer, I will solve it for you and it will you give you the exact answer which will be x² - 2x - 8
(x+2)(x-4)
Distribute
(x)(x) + (x)(-4)+(2)(x)+(2)(-4)
= x² - 4x + 2x - 8
= x² - 2x - 8
Here it is, we find the exam answer.

Thus, (x+2)(x-4) is the reciprocal of x² -2x - 8

I hope that's help !

How many terms are in a^2-ab+8b+b^2-1

DanielleElmas [232]

Remember that the terms of a polynomial are the parts of the polynomial separating by addition and subtraction; in other words, the parts separated by (+) and (-) signs. Knowing this, we can separate the terms of our polynomial:
$a^2-ab+8b+b^2-1$
- First term: $a^2$
- Second term: $-ab$
- Third term: $8b$
- Fourth term: $b^2$
- Fifth term: $-1$

We can conclude that there are 5 terms in the polynomial $a^2-ab+8b+b^2-1$ .
