simplify (x+3)(x^4-4x^2+5) Can you tell me the steps to take? I think I need to reorder it, but I don't know how.

Answer 1

Yes you do need to reorder it. I looks confusing right now

Answer 2

Just use the distributive property:

(x+3)(x^4-4x^2+5)
= (x+3)(x^4) + (x+3)(-4x^2) + (x+3)(5)
= x^5 + 3x^4 - 4x^3 - 12x^2 + 5x + 15
