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 follo

LiRa [457]

Answer:

Option d

Step-by-step explanation:

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

$ax(cx + d) = -b(cx+d) \\acx^2+x(ad+bc)+bd =0$

we can factorise this equation by grouping

$(acx^2+xad)+)xbc+bd) =0\\ax(cx+d) +b(cx+d) =0\\(ax+b)(cx+d) =0$

Equate each factor to 0 to get

$x=\frac{-b}{a} , \frac{-d}{c}$

Ratio of one solution to another would be

$\frac{-b}{a} / \frac{-d}{c} \\=\frac{ad}{bc}$

So ratio would be ad/bc

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

So option d is right
