Q. 19

# Mark the Correct alternative in the following:The number of roots of the equation isA. 0B. 1C. 2D. 3

given

(x+2) (x-5) (x+4) = (x-2) (x-3) (x+6)

x3+4x2-5x2-20x+2x2+8x-10x-40 = x3+6x2-3x2-18x-2x2-12x+6x+36

x2-22x-40 = x2-24x+36

4x = 76

x = 19

hence the given equation has only one solution.
