Q. What is the value of the discriminant of x2+5x=6 x^{2}+5 x=-6 ? How many real solutions does the equation have?\newline(A) The discriminant is 4949 and the equation has two real solutions.\newline(B) The discriminant is 11 and the equation has two real solutions.\newline(C) The discriminant is 11 and the equation has one real solution.\newline(D) The discriminant is 00 and the equation has one real solution.
  1. Rewrite equation: First, rewrite the equation in standard form: x2+5x+6=0x^2 + 5x + 6 = 0.
  2. Calculate discriminant: Next, calculate the discriminant using the formula Δ=b24ac\Delta = b^2 - 4ac, where a=1a = 1, b=5b = 5, and c=6c = 6.
  3. Plug in values: Plugging in the values, Δ=(5)2416=2524=1\Delta = (5)^2 - 4\cdot1\cdot6 = 25 - 24 = 1.
  4. Determine solutions: Since the discriminant Δ=1\Delta = 1, which is greater than 00, the equation has two distinct real solutions.
