They never intersect.

#### Explanation:

Let's solve the system and see!

#x + 1 = x^2 + 3#

#0 = x^2 - x + 2#

Now we apply the discriminant (the question asks how many solutions, not what they are).

#X = b^2 - 4ac#

#X = (-1)^2 - 4(1)(2)#

#X = -7#

Since

Hopefully this helps!

the answer is no intersect between two equation

#### Explanation:

because intersect means that ther is same Y between

and

so, lets think

do you under stand?
