Answer:
The discriminant can be used to find how many roots are in an equation.
Explanation:
The discriminant can be used to find how many roots are in an equation. The discriminant is √(b²-4ac), using the equation y=ax²+bx+c, and a, b, and c are coefficients.
If the discriminant is greater than zero (d>0), then there are 2 roots.
If the discriminant is equal to zero (d=0), then there is 1 root.
If the discriminant is less than zero (d<0), then there are no roots.
