Question

What is the discriminant of the quadratic equation 2x + 5x2 = 1?

Answer 1

2x +5x^2 = 1 so the quadratic equation will be

5x^2 +2x -1 = 0

formula for discriminant is D = b^2 -4ac so in this case

D = 2^2 -4(5)*(-1) = 4 -20*(-1) = 4+20 = 24

so the discriminant is equal 24

hope helped and is understandably
