#x= 3 or x = -2#
Explanation:
All the numbers in the equation are even, so divide through by 2.
#x^2 - x - 6 = 0" find factors"#
The factors of 6 which subtract to make 1 are 2 and 2.
#(x-3)(x+2) = 0#
If the answer to multiplication is 0, then one of the factors must be 0,
If #x-3 = 0, "then " x=3#
If #x+2 = 0, "then " x = -2#
