<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:
The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
