* 1.2.13 \ 5. Explain, step by step, how you solved the equation z^2 - z - 6 = 0 using factoring.
YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY
Your solution:
To use factoring to solve this equation you first find the common factors in the equation. z^2 - z - 6 = 0 = (z+3) (z-2) you then set both (z+3) (z-2) to 0 (z+3) = 0 then z = -3
(z-2) = 0 z = 2 the solution set is (-3,2)
