What is the discriminant of 3x^2-8x+5=5x^2

Move all terms to the left side of the equation and simplify.

-2 x2 - 8 x + 5 = 0 - 2 x2 - 8 x + 5 = 0

The discriminant of a quadratic is the expression inside the radical of the quadratic formula.

b2 - 4 (ac) b2 - 4 ac

Substitute in the values of aa, bb, and cc.

(-8) 2 - 4 (-2 ⋅5) - 8 2 - 4 - 2 ⋅5

Evaluate the result to find the discriminant./
