Question

X(x+1)(x+2)(x+3)+1=0

Answer 1

Answer:

x(×+1)(×+2)(×+3)+1=0

Step-by-step explanation:

×(×(×+2)+1(×+2)(×+3))+1

×(×^2+2× +1×+2 (×+3))+1

Answer 2

this can be done by substitution method

x×(x+3) × (x+1)(x+2)

(x ² +3x )( x ² +3x+3)

let x ² +3x=m

m(m+3)=0

m ² +3m=0

m[m+3]=0

m=0 or m=-3

x ² +3x=0. or. x ² +3x=-3

x=0 or x=-3. x=-3 or x =-6
