We then combine for the final answer. When we solve quadratic equations we get solutions called roots or places where that function crosses the x axis. Thus, these factors, when multiplied together, will give you the correct quadratic equation. If we know the solutions of a quadratic equation, we can then build that quadratic equation. Which of the following could be the equation for a function whose roots are at and? For example, a quadratic equation has a root of -5 and +3. Which of the following roots will yield the equation. We can make a quadratic polynomial with by mutiplying the linear polynomials they are roots of, and multiplying them out. Not all all will cross the x axis, since we have seen that functions can be shifted around, but many will.
The standard quadratic equation using the given set of solutions is. None of these answers are correct.
