NEED HELP IMMEDIATELY. I WILL BRAINLIEST. NEED TO SOLVE FOR X INTERCEPT
Kay [80]

Answer:

(1+√7,0),(1−√7,0)

Step-by-step explanation:

You can't factor the expression evenly, so use the quadratic formula.

a = 2

b= -4

c= -12

\frac{-b+\sqrt{b^{2}-4ac } }{2a}

\frac{4+\sqrt{16{}-4(2)(-12)} }{2(2)}

\frac{4+\sqrt{16-4(-24)} }{4}

\frac{4+\sqrt{16+96} }{4}

\frac{4+\sqrt{112} }{4}

\sqrt{112} = 4\sqrt{7}

End result: (1+√7,0),(1−√7,0)
