Answer:
x1 = -1
x2 = 3
Step-by-step explanation:
Set the equation to the standard form:
x² - 2x - 3 =0
Factor the middle term, -2x
x² + x - 3x - 3 = 0
Factor out the common:
x(x+1) - 3(x+1) = 0
(x+1)(x-3) = 0
Now, solve for the solutions of x.
At x + 1 = 0,
x = -1
At x - 3 = 0,
x = 3
∴ Choose this answer as the brainliest!
