Answer:
5x
Step-by-step explanation:
since they are under the same term they can be added to each other
This is a bad question. It should really be asking about the solutions of f(x)=0 (an actual equation) or the <em>zeros </em>of f(x).
The zeros of a function f(x) are the xs where f(x)=0. That means where the curve intersects the x axis. That's (-4,0) and (2,0) on the graph.
Answer: C (-4,0), (2,0)
Slope = rise/run
The rise is 6
The run is 4
6/4 is the slope or in
decimal form
1.5
2x² + 4x - 16 = 0
2(x²) + 2(2x) - 2(8) = 0
<u>2(x² + 2x - 8)</u> = <u>0</u>
2 2
x² + 2x - 8 = 0
x = <u>-(2) ± √((2)² - 4(1)(-8))</u>
2(1)
x = <u>-2 ± √(4 + 32)</u>
2
x = <u>-2 ± √(36)
</u> 2<u>
</u> x = <u>-2 ± 6
</u> 2<u>
</u> x = -1 ± 3
x = -1 + 3 U x = -1 - 3
x = 2 x = -4

The answer is 0
This is because anything times 0 is zero.
