Answer

Step 4: Simplify the expression to find the value of D. So, \(D = 36 - 20 = 16\).

Steps

Step 1 ：Step 1: Identify the coefficients from the quadratic equation. Here, a = 1, b = -6, c = 5.

Step 2 ：Step 2: Use the formula for the discriminant, \(D = b^2 - 4ac\).

Step 3 ：Step 3: Substitute the values of a, b and c into the formula. So, \(D = (-6)^2 - 4*1*5\).

Step 4 ：Step 4: Simplify the expression to find the value of D. So, \(D = 36 - 20 = 16\).
