You may be wondering, though, what if the discriminant is less than zero? Can you take the square root of a negative number? The answer is yes, it simply requires the use of imaginary numbers. The one exception to this rule is if b^2 – 4ac (called the discriminant) equals zero, because the square root of zero only equals zero.

Therefore, because the quadratic formula contains the square root of ( b² – 4ac), we must include the plus or minus in front, which results in two possible results for the square root and thus, two possible solutions to the quadratic equation. Therefore, whenever you take a square root of an expression, it is good practice to write +/- √ to express that there are two possible solutions. A quadratic equation has two roots or zeroes namely Root1 and Root2.

That is because two positive numbers multiplied together results in a positive number, but two negative numbers multiplied together also results in a positive number.įor example, the square root of 9 is plus or minus 3, because 3 x 3 = 9 and -3 x -3 = 9 as well. A quadratic is a second degree polynomial of the form: ax2 + bx + c 0 where a 0. Lets see how our equation solver solves this and similar problems. However, whenever one takes the square root of a positive value, there are always two possible answers, a positive answer and a negative answer.
