Solution
To find the x-intercepts, set the trinomial equal to 0. x 2 + 2x + 11 = 0 Use the quadratic formula to find the x-intercepts. Based on ax2 + bx + c, we have:
a = 1, b = 2, c = 11
Plugging into the quadratic formula results in these two answers:
Simplifying...
Since the square root is not a real number, there are no real number solutions. Therefore, there are no x-intercepts. |
