Answer:

0=  x^{2}+3x

Step-by-step explanation:

Since y= x+1,

x+1=x^{2}+4x+1

--> Bring x to the other side by changing sign.

1= x^{2}+4x-x+1

1= x^{2}+3x+1

--> Bring 1 to the other side by changing sign.

0= x^{2}+3x+1-1

0=  x^{2}+3x+0

(Note: When there's is no number in the LHS side, it becomes 0)

--> Bring 0 on the RHS, to LHS

0-0= x^{2}+3x

--> 0=  x^{2}+3x

Please mark me as brainliest!
