I found this question in my student book and am stumped, I was wondering if anyone could help?
Given that the quadratic equation ax^2+bx+c=0 has two solutions, show that the quadratic equation given by a^2 x^2=b^2 x-2acx-c^2, where a, b and c are constants and b≠0, also has two solutions.
I am used to using the discriminant and inequalities to find solutions involving k, but here all the coefficients are different letters.
