Answer:
To find the roots of the equation, replace
y with 0 and solve.
0 = x2 − 2x − 3
Rewrite the equation as
x2 − 2x − 3 = 0.
x2 − 2x − 3 = 0
Factor
x2 −2x − 3
using the AC method.
more steps...
(x−3) (x+1) = 0
Set
x − 3 equal to 0 and solve for x.
more steps...
x = 3 Set x + 1 equal to 0 and solve for x.
more steps...
x = −1 The solution is the result of x − 3 = 0 and x + 1 = 0.
x = 3, − .1
