Let a, b, c, and d be non-zero real numbers. if the quadratic equation ax(cx + d) = -b(cx+d) is solved for x, which of the following is a possible ratio of the 2 solutions?
(1) -ab/cd(2) -ac/bd(3) -ad/bc(4) ab/cd(5) ad/bc

Option d

Step-by-step explanation:

given that a, b, c, and d be non-zero real numbers.

we can factorise this equation by grouping

Equate each factor to 0 to get

Ratio of one solution to another would be

So ratio would be ad/bc

Out of the four options given, option d is equal to this

So option d is right
