Answer:
There are no real roots x^2 + 5x + 9
Explanation:
The general form of a quadratic equation is y = ax^2 + bx + c.
Normally, we find the factors of a quadratic equations by finding two numbers that represent the product of a and c, but also can be added to get b.
In the quadratic above, a = 1, b = 5, and c = 9.
The only four factors we could use to get 9 are 1 * 9, -1 * -9, 3 * 3, and -3 * -3. None of these add up to 5.
The main reason why there are no real roots is because the quadratic equation lies above the x-axis and never intersects it.
