Final answer:
To complete the equation with solutions of -5 and 7, use the fact that solutions of a quadratic equation are values of x that make the equation equal to zero. The completed equation is x² + 2x - 35 = 0.
Step-by-step explanation:
To complete the equation with solutions of -5 and 7, we can use the fact that the solutions of a quadratic equation are the values of x that make the equation equal to zero. Let's call the missing terms a and b. Since the equation has solutions of -5 and 7, we know that (x + 5) and (x - 7) are factors of the equation.
Therefore, the completed equation is:
x² + 2x - 35 = 0
