What is the discriminant of the quadratic equation 0 = –x2 4x – 2?

Step-by-step explanation:

Given is a quadratic equation of the form

WE know that for any quadratic equation of the form

the discriminant would be

The discriminant determines the nature of roots of the quadratic equation, namely, real, rational or equal roots.

Here we have for the given equation

discriminant =

Thus we have discriminant as positive but not perfect square

Hence roots would be distinct, irrational and real.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
