Find the roots of

Given Equation:


Taking L.C.M, we get,




Cross-multiplying, we get,


-9 = 4(x2 – 3x)


-9 = 4x2 – 12x


4x2 – 12x + 9 = 0


Now, we know that for an equation ax2 + bx + c = 0, roots are given by,


x


Comparing 4x2 – 12x + 9 = 0 with ax2 + bx + c = 0


a = 4, b = -12 and c = 9


Therefore,





Hence, the roots of the equation are and .
