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)

Answer:

$y= -2+\frac{2}{3}x$

Step-by-step explanation:

Multiply both sides by 2

2x=3y+6

Move variable to the left-hand side and change its sing

-3y=6-2x

Divide both sides of the equation by -3

$y= -2+\frac{2}{3}x$
