Solve the equation by graphing. if exact roots cannot be found, state the consecutive integers between which the roots are located.
-2x^2 + 3x + 4 =0
one solution is between 2 and 0, while the other solution is between 3 and –1.
one solution is between 0 and –1, while the other solution is between 2 and 3.
one solution is between –2 and –3, while the other solution is between 0 and 1.
one solution is between 2 and –1, while the other solution is between 0 and 3.

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.

correct answer is b. 27/8
