Remember it says not to solve the equation. Thanks! This question is from textbook college algebra
You can put this solution on YOUR website! Use the discriminant to determine the nature of the rools of each equation.
:
10x^2 + x = 21
Put the equation in the standard form:
10x^2 + x - 21 = 0
:
Using the form ax^2 + bx + c, in your equation: a = 10, b = 1, c = -21
:
The discriminant: D = b^2 - (4 * a * c)
:
D = 1^2 - (4 * 10 * -21)
D = 1 - (- 840)
D = 1 + 840
D = +841
:
Since D > 0, there are 2 real number solution that are not equal.
