Question

2x^3+10x^2+5x+25 and x^3+5x^2-x-5​

Answer 1

If you want to divide these two,

Answer

(2x³ +10x² +5x +25) ÷ x³ + 5x² -x -5,

You can factorise 2x³ +10x² +5x +25 as (x+5)(2x²+5) and x³ + 5x² -x -5 as (x+5)(x²+5) .

So it cancels out (x+5) term and you're left with:

$\frac{2 {x}^{2} + 5 }{ {x}^{2} + 5 }$
