For each quadratic equation, determine the solutions using the Zero Product Property or the Quadratic Formula. Then verify your answer using a table or a graph of the related function. For example, for Problem 1, use a graph or table of y = x2 + 2x – 15 to verify your algebraic solution. x2 + 2x – 15 = 0 2x2 + 7x + 3 = 0 x2 + 4x = 17 3x2 = 6 5. Write a quadratic equation in standard form that has solutions x = 2 and x = –2. 6. Write a quadratic equation in standard form that has solutions x = 2 ± 3.
