Question

x.(x+1).(x+2).(x+3)=3

Answer 1

\(x\left(x+1\right)\left(x+2\right)\left(x+2\right)=3\)

\(\Rightarrow\left(x^2+x\right)\left(x^2+2x+2x+2^2\right)\)

\(\Rightarrow\left(x^2+x\right)\left(x+2\right)^2\)

Answer 2

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

⇒(x^2+x)(^x2+2x+2x+2^2)

⇒(x^2+x)(x+2)^2

Answer 3

x . ( x + 1 ).( x + 2 ) .( x + 3 ) = 3

=> ( x² + x ) ( ^x2 + 2x + 2x + 2² )

=> ( x² + x )(x + 2²)
