What do you do when Root(b^2-4ac) is negative? because you can't have a negative under a root right?
The quadratic formula is a mathematical formula used to solve quadratic equations of the form ax^2 + bx + c = 0. It is written as x = (-b ± √(b^2 - 4ac)) / 2a.
When the quadratic formula has a negative number in the square root, it means that the equation has no real solutions. This is because the square root of a negative number is not a real number.
To simplify the quadratic formula with a negative number in the square root, you can use the imaginary unit, i, which represents √(-1). The simplified form of the quadratic formula would be x = (-b ± i√(4ac - b^2)) / 2a.
Yes, the quadratic formula can produce complex solutions when the discriminant (b^2 - 4ac) is negative. This means that the solutions will involve the imaginary unit, i, and will not be real numbers.
You would use the quadratic formula with a negative number in the square root when the discriminant (b^2 - 4ac) is negative. This indicates that the equation has no real solutions and the solutions will involve the imaginary unit, i.
