Question

Solve x^2-2x-3=0 by graphing
A. X=-1,3
B. X=-1,3
C. No solution
D. X=-1,3

Answer 1

Answer: x= -1, 3

Explanation:

`x^2 -2x -3=0`

It is asking what is x when y is 0, so find the x-intercepts

to solve by graphing: type equation into desmos or a graphing calculator(Y=, GRAPH)

the points of intersection with the x axis are (-1,0) and (3,0)

so x=-1, 3

Answer 2

The answer is 3, -1.
