Which of these equations best describes the points of intersection of the curve and the line?
-
A.
(x^2 + 5x – 6 = 0) -
B.
x2 – 5x – 6 = 0 -
C.
x2 + x – 6 = 0 -
D.
x2 – x – 6 = 0
Correct Answer: Option C
Explanation
The roots are -3 and 1
x = -3 and x = 1
y = (x + 3)(x – 1)
= x2 – x + 3x – 3
y = x2 + x – 6 = 0
