Sum

Solve the following quadratic equation using formula method only

3"x"^2 - 5"x" + 25/12 = 0

Solution

3"x"^2 - 5"x" + 25/12 = 0

a = 3 ; b = -5 ; c = 25/12

D = b2 - 4ac

= (-5)^ 2 - 4(3)(25/12)

= 25 - 25

= 0

x = (- "b" ± sqrt ("b"^2 - 4 "ac"))/(2a)

x = (-(-5) +- 0)/6

x = 5/6

Is there an error in this question or solution?
