Question

Which of these equations best describes the points of intersection of the curve and the line?

Options

A) x2 + 5x - 6 = 0

B) x2 - 5x - 6 = 0

C) x2 + x - 6 = 0

D) x2 - x - 6 = 0

The correct answer is 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
