Activity No4 :Determine nature of roots of the quadratic equation.

    3y² + 4y - 8 = 0

Solution: Compare 3y² + 2x - 8 = 0 with ax² + bx + c = 0.

    ∴a = , b = 2, c = - 8,

           ∴ b² - 4ac = 2² - 4 X 3 X

           ∴b² - 4ac = + 96

           ∴b² - 4ac =

     ∴ b² - 4ac > 0.
∴ The roots of the equation are real and unequal.
