5. which of the following is a solution to x2 – x – 6 = 0?
a
b
c
d
-3
-2
-1
2

x² - x - 6 = 0

x²- (3 - 2)x - 6 = 0

x² - 3x + 2x - 6 =0

x(x - 3) + 2(x - 3) = 0

(x - 3) (x + 2) = 0

x - 3 = 0

x = 3

x + 2 = 0

x = -2

x= 3 and x = -2

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
