Find the Discriminant x^2-6x+9=0

Problem

x2−6*x+9=0

Solution

1. Identify the coefficients a b and c from the quadratic equation in the standard form a*x2+b*x+c=0

a=1

b=−6

c=9

2. Recall the formula for the discriminant D

D=b2−4*a*c

3. Substitute the values of a b and c into the formula.

D=(−6)2−4*(1)*(9)

4. Simplify the expression by calculating the square and the product.

D=36−36

5. Calculate the final value.

D=0

Final Answer

D=0
