<u>x-intercepts are found by setting y=0</u>
![y=2x^2-8x-10\rightarrow0=2x^2-8x-10](https://tex.z-dn.net/?f=y%3D2x%5E2-8x-10%5Crightarrow0%3D2x%5E2-8x-10)
<em>factor out a 2</em>
![0=2(x^2-4x-5)\rightarrow0=x^2-4x-5](https://tex.z-dn.net/?f=0%3D2%28x%5E2-4x-5%29%5Crightarrow0%3Dx%5E2-4x-5)

![0=(x-5)(x+1)](https://tex.z-dn.net/?f=0%3D%28x-5%29%28x%2B1%29)
<em>roots should be </em>x=-1,5
therefore,
x-intercepts are (-1,0) and (5,0)
<u>
</u><u>y-intercepts are found by setting x=0</u>
![y=2x^2-8x-10\rightarrow y=2(0)^2-8(0)-10](https://tex.z-dn.net/?f=y%3D2x%5E2-8x-10%5Crightarrow%20y%3D2%280%29%5E2-8%280%29-10)
![\rightarrow y=0-0-10=-10](https://tex.z-dn.net/?f=%5Crightarrow%20y%3D0-0-10%3D-10)
therefore,
y-intercept is (0,-10)
5 * 3 does not tell you the total number of flash cards in 5 piles because you don't know how many cards are in each pile.
