(3x - 10x2 +17) / (x - 2)

\frac{3x-10x\cdot \:2+17}{x-2}=\frac{-17x+17}{x-2}

Sorry, I don't know how to type this properly, my computer only lets me type in this format.

Hope it helped!

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
