Answer:
x² +2x -3 = 0
Step-by-step explanation:
Given the zeros of a quadratic function the factored form is easily found. There is a factor (x -p) for each zero x = p. Here, the factored form of the function is ...
0 = (x -(-3))(x -1) = (x +3)(x -1)
In standard form, this is ...
x(x -1) +3(x -1) = 0
x² +2x -3 = 0 . . . . . . the terms have no common factors
