NOTE: Ultimate result is 0. Thus , for each equal positive or negative value of x , this equation holds true. Another thing is that there is multiplication relationship among all the items.

Given,

$$(x - 2)(x + 2)(x - 3)(x + 5)(x + 9) = 0$$

we will try to take one positive and one positive value.

x + 9 = 0

x = -9.............This is least

one positive value.

x - 3 = 0

x = 3.

Required Ratio : 3/-9 = - 1/3.

A is the correct answer. If (x - 2)(x + 2)(x - 3)(x + 5)(x + 9) = 0, what is the ratio of the   [#permalink] 07 Mar 2019, 02:55
