How to solve a square root with a negative
WebThen solve for x x as usual, just like in Examples 1 and 2. The solutions to this quadratic formula are x = 3 x = 3 and x = - \,3 x = −3. Example 4: Solve the quadratic equation below using the Square Root Method. The two parentheses should not bother you at all. The fact remains that all variables come in the squared form, which is what we want. WebThe square root of a negative number does not exist among the set of Real Numbers. When problems with negatives under a square root first appeared, mathematicians thought that a solution did not exist. They saw equations such as x2 + 1 = 0, and wondered what the solution really meant.

WebBut x could be positive or negative (though not zero, obviously). To solve this absolute-value equation, we must consider each of the two cases. If x is positive, then we can remove the absolute-value bars without changing anything: If x > 0, then x = x, so x = x = 2 WebAnother solution is − 3 ≈ − 1.732. The same as the previous solution, just multiplied by − 1. There are two other solutions: x = − 3 and x = − − 3, which are roughly 1.732, the former multiplied by i and the latter multiplied by − i. These are all the same distance away from 0.
