Answer:

(1,0)

Step-by-step explanation:

we can't factor this so we'll use the quadratic formula

[tex]\frac{-b+\sqrt{b^2-4ac} }{2a}\\\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex]

(use both of them because usually there  are two zeroes)

We have

[tex]\frac{2+\sqrt{4-4}}{2}=\frac{2}{2}=1[/tex]

Therefore the x intercept is just (1,0)
