Q. For the following quadratic equation, find the discriminant.\newline6x2+53x180=3x27x -6 x^{2}+53 x-180=-3 x^{2}-7 x \newlineAnswer:
  1. Simplify the Equation: First, we need to simplify the given equation by moving all terms to one side to get a standard quadratic equation of the form ax2+bx+c=0ax^2 + bx + c = 0.
    6x2+53x180=3x27x-6x^2 + 53x - 180 = -3x^2 - 7x
    Add 3x23x^2 to both sides:
    6x2+3x2+53x180=7x-6x^2 + 3x^2 + 53x - 180 = -7x
    Combine like terms:
    3x2+53x180=7x-3x^2 + 53x - 180 = -7x
    Now, add 7x7x to both sides:
    3x2+53x+7x180=0-3x^2 + 53x + 7x - 180 = 0
    Combine like terms:
    3x2+60x180=0-3x^2 + 60x - 180 = 0
  2. Find the Discriminant: Now that we have the quadratic equation in standard form, we can find the discriminant using the formula b24acb^2 - 4ac, where aa, bb, and cc are the coefficients from the quadratic equation ax2+bx+c=0ax^2 + bx + c = 0. For our equation, a=3a = -3, b=60b = 60, and c=180c = -180. Let's calculate the discriminant: Discriminant = b24acb^2 - 4ac Discriminant = (60)24(3)(180)(60)^2 - 4(-3)(-180)
  3. Calculate the Discriminant: Perform the calculations:\newlineDiscriminant = 36004(3)(180)3600 - 4(-3)(-180)\newlineDiscriminant = 36004(540)3600 - 4(540)\newlineDiscriminant = 360021603600 - 2160\newlineDiscriminant = 14401440
