First get the equation into the form: Ax^2 + Bx + C = 0 (the quadratic equation).. We do this by subtracting 10x both sides (to get it on the other side).. 9x^2 + 2 = 10x 9x^2 - 10x + 2 = 10x - 10x 9x^2 - 10x + 2 = 0 Now the discriminant is: b^2 - 4ac The quadratic equation is Ax^2 + Bx + C = 0 Here, A = 9, B = -10 and C = 2 so plug them in... (-10)^2 - 4 (9)(2) = 100 - 4 (18) = 100 - 72 = 28 <--- answer...
