Factorise the following x^4+x
Ostrovityanka [42]

Answer:

\large\boxed{x^4+x=x(x^3+1)=x(x+1)(x^2-x+1)}

Step-by-step explanation:

x^4=x\cdot \underbrace{x\cdot x\cdot x}_{3}=x\cdot x^3\\\\x=x\cdot 1\\\\x^4+x=\bold{x}\cdot x^3+\bold{x}\cdot1=\bold{x}\cdot(x^3+1)\\\\\text{used the distriburtive property:}\ a(b+c)=ab+ac

\text{If you want complete factorise, then:}

x^3+1=x^3+1^3    \text{use}\ a^3+b^3 = (a + b)(a^2 - ab + b^2)

x^4+x=x(x^3+1)=x(x+1)(x^2+(x)(1)+1^2)=x(x+1)(x^2+x+1)
