Factor the expression: 2x - 5x - 3
O A. (2x-3)(x + 1)
O B. (2x+3)(x - 1)
OC. (2x - 1)(x+3)
• D. (2x + 1)(x - 3)

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

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.
