Y=x to the second power + 5x+1
who can find the answer to this

Before you look for the answer, you need to know clearly what the question is.
I'm not sure you're quite there yet.

The 'solution' (answer) to an equation is a number, or a set of numbers, that you can write in place of all the variables (letters) in the equation, and then have an equation with only numbers in it that's a true statement.

Your equation has two variables in it . . . 'x' and 'y' .  A solution is a pair of numbers that you can write in place of 'x' and 'y' and wind up with a statement that's true.

There are an infinite number of pairs that can do that.  Here are a few of them:

x=-2 ... y=-5
x=-1 ... y=-3
x=0 y= 1
x=1 y= 7
x=2 y=11
 

The answer is
