Question

For which values is this undefined (what numbers makes the denominator 0)

Answer 1

x = -6 and x = 1

Explanation:

For the fraction to be undefined, find the zeros of the polynomial of the denominator.

• x² + 5x - 6 = 0
• x² - x + 6x - 6 = 0
• x(x - 1) + 6(x - 1) = 0
• (x + 6)(x - 1) = 0
• x = -6 and x = 1
