<h2>
The all roots are equation are 1, - 1 and - 2.</h2>
Step-by-step explanation:
The given cubic polynomial:
k(x) =
+ 2
- x -2
To find, the all roots are
+ 2
- x -2 = ?
∴ k(x) =
+ 2
- x -2
⇒
+ 2
- x -2 = 0
⇒
(x + 2) - 1(x + 2) = 0
⇒ (
- 1)(x + 2) = 0
⇒
- 1 = 0 and x + 2 = 0
⇒
- 1 = 0
⇒
= 1
⇒ x = ± 1 = 1, - 1
or, x + 2 = 0
⇒ x = - 2
Thus, the all roots are equation are 1, - 1 and - 2.
Answer:
B
Step-by-step explanation:
Answer: Yes!
Step-by-step explanation:
If the x and y coordinates form proportional relationships, then there is some non-changing number (a constant) that when multiplied times x will create y. In this example, that number is 3 (y = 3x), and is called the constant of proportionality. ... It is a positive number.
