Question

Solve Quadratic : a(x^2+1)-x(a^2+1)=0​

Answer 1

Answer:

x=a

Step-by-step explanation:

in equations which look identical on either sides of the equal sign. you should rely on assuming a relation btw a and x that would satisfy the equation and try to prove it.

here by putting

x=a we can clearly see that

a(x^2+1)=x(a^2+1)

will turn into

a(a^2+1)=a(a^2+1)

which is clearly true and hence the relation btw x and a is

x=a.

[as there are 2 variables and only 1 equation

we can only find their relation and not an exact value of the variables.]
