The given equation is a polynomial of degree 2 and hence a quadratic equation.

The given equation can be written and solved as follows:


y+=+x%5E2+%2B+3x+%2B+2


y+=+x%5E2+%2B+2x+%2B+x+%2B+2+

+y+=+x%28x+%2B+2%29+%2B+1%28x+%2B+2%29+

y+=+%28x+%2B+1%29%28x%2B2%29

hence, the zeroes of the polynomial is x = -2, -1

The graph of the given quadratic is :


+graph%28+400%2C+400%2C+-15%2C+15%2C+-15%2C+15%2C+x%5E2+%2B+3x+%2B+2+%29+
