Question

15) If a curve intersects x -axis at (2,0) and (-2,0) then zeroes of a polynomial are

2,2
-2,-2
2,-2
None​

Answer 1

`2\ and\ -2`

Explanation:

If a polynomial intersects the x-axis at (2,0) and (-2,0)

Then the zeroes are at x=2 and x=-2

(Outside of the question)

To find factors using the zeroes, we must have one side of the equation equal to zero.

x=2

x-2=0

factor (x-2)

x=-2

x+2=0

factor (x+2)
