Answer:
3![\frac{6}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B25%7D)
Step-by-step explanation:
3.24 = 3 + .24
3 = 3 and .24 = 24/100
24/100 can be simplified to 6/25
Answer:
![y=6x^2-5x+1](https://tex.z-dn.net/?f=y%3D6x%5E2-5x%2B1)
Step-by-step explanation:
If the quadratic equation has a root at
then when
, ![y=0](https://tex.z-dn.net/?f=y%3D0)
![\implies x=\dfrac13](https://tex.z-dn.net/?f=%5Cimplies%20x%3D%5Cdfrac13)
![\implies 3x=1](https://tex.z-dn.net/?f=%5Cimplies%203x%3D1)
![\implies 3x-1=0](https://tex.z-dn.net/?f=%5Cimplies%203x-1%3D0)
If the quadratic equation has a root at
then when
, ![y=0](https://tex.z-dn.net/?f=y%3D0)
![\implies x=\dfrac12](https://tex.z-dn.net/?f=%5Cimplies%20x%3D%5Cdfrac12)
![\implies 2x=1](https://tex.z-dn.net/?f=%5Cimplies%202x%3D1)
![\implies 2x-1=0](https://tex.z-dn.net/?f=%5Cimplies%202x-1%3D0)
Therefore, ![y=(3x-1)(2x-1)](https://tex.z-dn.net/?f=y%3D%283x-1%29%282x-1%29)
![\implies y=6x^2-5x+1](https://tex.z-dn.net/?f=%5Cimplies%20y%3D6x%5E2-5x%2B1)
