What is meant by Quadratic Calculator?

Quadratic is the second word in the equation, meaning squared. When we look at a quadratic equation, we get two different answers depending on whether we take the square root of both sides or not.

 

If we take the square root on both sides, then the answer would be (x - 2)^(1/2).

 

If we don't take the square root on either side of the equation, then the answer would just be x + 2.

 

The square root symbol looks like this: ^(1/2). We don't have to worry about what kind of root it is; it's not a real root. In fact, it's really just a power root. A power root is actually a number followed by ^. So for example, if we wanted to find a cube root of 6, we would write 6^(1/3), instead of using the root sign.

 

Here's how you might use a power root to solve a problem. If we want to know what the value of x is, we could multiply by 4. That means that we need to take the square root of (x * 4) 4*x^(1/2), which gives us (x - 2)*x^(-1/2) 4*x, which gives us (x-2) 4*sqrt(x). Since 4*sqrt(16) 16, we know that x 8. This may help you understand the concept of a power root better.
