4x + 8 - 36 first subtract 36 from 8 to get the simplified equation 4x + (-28), or 4x - 28. As you cannot combine these terms, this is as far as you can go. Hope this helps! :)
Number: n
square of number: n^2
sum of n and n^2 is n+n^2=20
Rewriting this equation, we get n^2+n-20=0 = (n+5)(n-4) = 0
Then n+5=0 and n-4=0, so n = -5 and n = 4.
You must check both results. It could happen that both are correct, or that only one is correct.
