hi bobbym here Agnishom solve all  the problems and he also given hints. i think still you have some confusion.I will explain clearly along with formulas

problem:x^4+8x^2+144
solution: [(x^2)^2+2(x^2)(12)+(12)^2]-16x^2    Formula:(a+b)^2=a^2+2ab+b^2

here (x^2+12)^2 = (x^2)^2+2(x^2)(12)+12^2
If u solve this, the result be x^4+24x^2+144

But in the given question we have 8x^2, we got 24x^2 for that we are subtracting 16x^2 from our result

so the equation be [(x^2)^2+2(x^2)(12)+12^2]-16x^2
                           
                             [(x^2+12)^2]-16x^2   

                             (x^2+12)^2-(4x)^2      Formula(a+b)(a-b)=a^2-b^2

here a=x^2+12  b=4x,      [x^2+12+4x][x^2+12-4x]

Therefore[x^2+4x+12][x^2-4x+12]

That was a joke. I loved playing with those people and teasing them was my way of showing affection.

I am sorry.

But why do you think that if two people have different opinions, one if them is crazy?

I did not mean you. I mean the person who wrote it.

You do not have to read the math just the chatting.

Agnishom

I will. But I am not mentally feeling ready for such a complicated math problem.

I did not get it from any website. It is the translation of a joke I found in a magazine years ago
