When solving using the quadratic formula, what does the discriminant tell you about the nature of the roots?

The discriminate is the part under the square root of the formula and gives you the amount of solutions

If the discriminate is positive there are 2 solutions, if it is 0 there is a single solution and if it is negative then there is no solution (in the real numbers), because the root is not defined for negative numbers

<h3>what is equation?</h3>

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). Equations can be solved to find the value of an unknown variable representing an unknown quantity. If there is no 'equal to' symbol in the statement, it means it is not an equation. It will be considered as an expression.

As, per the given situation the equation can be

2125 + 49.99 t = 39.95 t

10.4 t= 2125

t= 2125 / 10.4

t= 21250/104

t= 204.3269230769231
