Discriminant for the quadratic equation [tex]2x^2+x-3=0[/tex] is [tex]d=25[/tex]
How to find the d Discriminant of the quadratic equation ?
We know that the standard quadratic equation
[tex]ax^2+bx+c=0[/tex]
Discriminant of the equation is [tex]d=b^2-4ac[/tex]
Equation given in the question is
[tex]2x^2+x-3=0[/tex]
So we can find the values of [tex]a,b,c[/tex]
[tex]a=2\\b=1\\c=-3[/tex]
Substitute the values
[tex]d=1^2-4*2*(-3)\\d=1+24\\d=25[/tex]
