Question

x cube + x square + X + 1​

Answer 1

Step-by-step explanation:

First, group the two terms on the left and the two terms on the right as:

#(x^3 + x^2) + (x + 1)#

Now, factor out an #x^2# from the term on the left to give:

#((x^2 xx x) + (x^2 xx 1)) + (x + 1)#

#x^2(x + 1) + (x + 1)#

#(x + 1)# can also be written as #1(x + 1)# giving:

#x^2(x + 1) + 1(x + 1)#

We can now factor out an #(x + 1)# from each term giving:

#(x + 1)(x^2 + 1)#

Answer 2

x^3+ x^2+x+1
Take common by grouping the terms
x^2(x+1)+1(x+1)

(x+1)(x^2+1)
