Question

x cube + x square + X + 1

Answer 1

x 2(x + 2) - 16(x + 2) Factor x + 2 out = (x + 2)( x 2 - 16) The term (x 2 - 16) is the difference of two squares and can be factored using formula 1 above = (x + 2)(x + 4)(x - 4 ...

Answer 2

x³ +x² +x +1

x²(x+1) +1(x+1)

(x²+1)(x+1)

x=-1 OR = -1

I hope this will help you
