What is the discriminant (D) of the equation \\(3x^2-5x+2=0\\)?

Answer and explanation

Correct answer: 1

For a quadratic equation \\(ax^2+bx+c=0\\\), the discriminant is given by \\(D=b^2-4ac\\\). Here, \\(a=3, b=-5, c=2\\\), so \\(D=(-5)^2-4(3)(2)=25-24=1\\\). Since \\(D>0\\\), the equation has two distinct real roots. In an exam, remember to include the negative sign of \\(b\\\) before squaring it.
