Question

Factorise the above....​

Answer 1

Step 1 :

Equation at the end of step 1 :

0-(((((x4)+(5•(x3)))+7x2)+5x)+6) = 0

Step 2 :

Equation at the end of step 2 :

0-(((((x4)+5x3)+7x2)+5x)+6) = 0

Step 3 :

Step 4 :

Pulling out like terms :

4.1 Pull out like factors :

-x4 - 5x3 - 7x2 - 5x - 6 =

-1 • (x4 + 5x3 + 7x2 + 5x + 6)
