Answer:
24
Step-by-step explanation:
the discriminant of the quadratic equation [tex]2x + 5x^2 = 1[/tex]
Write the equation in the form of ax^2 +bx+c=0
[tex]2x + 5x^2-1=0[/tex]
[tex]5x^2+2x-1=0[/tex]
To find out discriminant we use formula
[tex]b^2-4ac[/tex]
From the given equation the value of a=5, b= 2 and c=-1
Now we plug in the values in the formula
[tex]b^2-4ac=2^2-4(5)(-1)=24[/tex]
