Answer: x²-22/3x+7/3=0

Step-by-step explanation:

For the solutions to be 1/3 and 7, the equations must be x-1/3 and x-7 because they will equal zero.

(x-1/3)(x-7)=???

x·x= x²

x·(-1/3)=(-1/3x)

x·(-7)=(-7x)

(-7)·(-1/3)=7/3

x²-1/3x-7x+7/3=0 ⇒ x²-22/3x+7/3=0

Since this is in the quadratic form (ax²+bx+c), this is the final answer.

Hope that this helped! Have a great day!!
