Q. Find the discriminant.\newline9s2+6s+1=09s^2 + 6s + 1 = 0
  1. Identify coefficients: Identify the coefficients of the quadratic equation.\newlineThe quadratic equation is in the form ax2+bx+c=0ax^2 + bx + c = 0. For the equation 9s2+6s+1=09s^2 + 6s + 1 = 0, the coefficients are:\newlinea = 99\newlineb = 66\newlinec = 11
  2. Calculate discriminant: Calculate the discriminant using the formula D=b2−4acD = b^2 - 4ac.\newlineSubstitute the identified values into the formula:\newlineD=(6)2−4×9×1D = (6)^2 - 4 \times 9 \times 1
  3. Perform calculations: Perform the calculations to find the value of the discriminant.\newlineD=36−4×9×1D = 36 - 4 \times 9 \times 1\newlineD=36−36D = 36 - 36\newlineD=0D = 0
