Question

Hey, I couldn't find the answer to this question "Solve (x +1)(x +2)(x +3)(x+ 4)=120?" , Please help out by answering

BeginnerMotivation — Failing to remember all of my A+ Algebra skills… :)

My “go-to” suggests that we would divide “x” out of (x+1)(x+2)(x+3)(x+4), and then divide “x” from the 120.

This would make: 1*2*3*4 = 120/x

… 24 = 120/x

… 24x = 120

… x = 5

I realize I have “calculated” the wrong answer. Would anyone be so kind and explain the best way to “re-think” this?

Thanks again. Love this blog.
