The discriminant is the part of the quadratic formula underneath the square root symbol: b²-4ac. The discriminant tells us whether there are two solutions, one solution, or no solutions.

It determines if the solution is equal, less than , or more than zero so if it’s equal you only have one solution but if it’s less than so it’s an imaginary graph that doesn’t have solution or more than means it has more than a solution

10% of an amount is 6.2 . Wirk out the original account<br>​
lesantik [10]

Answer:

the original amount was 62

Step-by-step explanation:

You can use the part over whole formula like this:

\frac{part}{whole} = ( \frac{6.2}{?} * \frac{10}{100})\\  ? = 62

why?

because we know that 10% = 10/100, we can easily find out the answer by cross multiplying

? * 10 (let's use x, instead of ?)

=10x

6.2 * 100

= 620

Now we have an equation that looks like this: 10x = 620

By using the inverse operation tool (dividing each side by 10 to isolate x) we have:

x (or ?) = 62
