Since only is seen in the answer choices, it is the correct answer. If the roots of the equation are at x= -4 and x=3, then we can work backwards to see what equation those roots were derived from. For example, a quadratic equation has a root of -5 and +3. Not all all will cross the x axis, since we have seen that functions can be shifted around, but many will. These correspond to the linear expressions, and.
Expand their product and you arrive at the correct answer. These two terms give you the solution. How could you get that same root if it was set equal to zero? Thus, these factors, when multiplied together, will give you the correct quadratic equation. The standard quadratic equation using the given set of solutions is. When we solve quadratic equations we get solutions called roots or places where that function crosses the x axis. If the quadratic is opening down it would pass through the same two points but have the equation:.
