Submit Use the quadratic equation x2−2x−3=0 to answer the questions. A: What are the solutions to the quadratic equation? B: Which statements accurately interpret the solutions? Select one answer for question A, and select two answers for question B. B: Since the solutions are x=1 or x=−3, the factors of the quadratic expression x2−2x−3 are (x−1) and (x+3). B: Since the quadratic equation has two real solutions, the graph of the quadratic equation intercepts the x-axis at (−3,0) and (1,0). B: Since the quadratic equation has two real solutions, the graph of the quadratic equation intercepts the x-axis at (−1,0) and (3,0). A: x=1 or x=−3 A: x=1 or x=3 B: Since the solutions are x=1 or x=−3, the factors of the quadratic expression x2−2x−3 are (x−1) and (x+3). B: Since the quadratic equation has two real solutions, the graph of the quadratic equation intercepts the x-axis at (1,0) and (3,0). B: Since the solutions are x=−1 or x=3, the factors of the quadratic expression x2−2x−3 are (x+1) and (x−3). A: x=−1 or x=3
