Full solution

Q. Find the discriminant.\newline5x25x+2=05x^2 - 5x + 2 = 0
  1. Identify coefficients: Identify the coefficients aa, bb, and cc from the quadratic equation 5x25x+2=05x^2 - 5x + 2 = 0 by comparing it to the standard form ax2+bx+c=0ax^2 + bx + c = 0. Here, a=5a = 5, b=5b = -5, and c=2c = 2.
  2. Recall discriminant formula: Recall the formula for the discriminant of a quadratic equation, which is D=b24acD = b^2 - 4ac.
  3. Substitute values: Substitute the identified values into the discriminant formula: D=(5)24×5×2D = (-5)^2 - 4 \times 5 \times 2.
  4. Calculate discriminant: Calculate the discriminant: D=2540D = 25 - 40.
  5. Simplify result: Simplify the result to find the value of the discriminant: D=2540=15D = 25 - 40 = -15.
