x=(-15±√(79) all over 4
Step-by-step explanation:
You can do this in a few ways but I used the quadratic formula for it. Just plug the numbers into this equation: x= -b ± √(b-4ac) all over 2a.
In this case a=2, b=15, c=-8
Also, there wasn't an "x" behind 15 so I'm doing this by assuming that there is one.
C. (–4, 0), (–2, 0), (1, 0), and (3, 0).
The points where the graph intersects the x axis have y coordinates of zero and the given x coordinates.
(–4, 0), (–2, 0), (1, 0), and (3, 0) is the answer.
-3x+2
Since it's addition you just combine all like terms so,
5x+4
-8x-2
= -3x+2
