Answer

Explanation:

Step1: Rewrite the equation in standard form

The standard form of a quadratic equation is (ax^{2}+bx + c=0). Given (2x^{2}-9x + 2=-1), add (1) to both sides: (2x^{2}-9x+3 = 0) Here (a = 2), (b=-9), (c = 3)

Step2: Calculate the discriminant

The discriminant formula is (\Delta=b^{2}-4ac) Substitute (a = 2), (b=-9), (c = 3) into the formula: (\Delta=(-9)^{2}-4\times2\times3) (=81 - 24) (=57)

Step3: Determine the nature of the roots

Since (\Delta=57>0), when (\Delta>0), the quadratic equation (ax^{2}+bx + c = 0) has two distinct real roots.

Answer:

The discriminant is greater than 0, so there are two real roots.
