Q. Find the discriminant.\newline4q2+8q+4=04q^2 + 8q + 4 = 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 4q2+8q+4=04q^2 + 8q + 4 = 0, the coefficients are:\newlinea = 44\newlineb = 88\newlinec = 44
  2. Calculate discriminant: Calculate the discriminant using the formula D=b2−4acD = b^2 - 4ac.\newlineSubstitute the identified values into the formula:\newlineD=(8)2−4×4×4D = (8)^2 - 4 \times 4 \times 4
  3. Perform calculations: Perform the calculations to find the value of the discriminant.\newlineD=64−4×4×4D = 64 - 4 \times 4 \times 4\newlineD=64−64D = 64 - 64\newlineD=0D = 0
