Q. What is the discriminant of the quadratic equation −8x2+8x−3=0 ?32−160−32160
Identify Coefficients: The discriminant of a quadratic equation in the form ax2+bx+c=0 is given by the formula D=b2−4ac. We need to identify the coefficients a, b, and c from the given equation.
Find Coefficients: In the equation −8x2+8x−3=0, the coefficient a is −8, the coefficient b is 8, and the coefficient c is −3.
Calculate Discriminant: Now we will calculate the discriminant using the formula D=b2−4ac. Substituting the values we get D=(8)2−4⋅(−8)⋅(−3).
Substitute Values: Calculating the discriminant, we have D=64−4×8×3.
Simplify Calculation: Further simplifying, we get D=64−96.
