What is the product of 6x – 5 and 8x + 3 Your 14x – 2 -2x – 8 6x2 -13x +15 48x2 -22x -15

48x^2 - 22x - 15

Step-by-step explanation:

(6x - 5)(8x + 3)

48x^2 + 18x - 40x - 15

48x^2 - 22x - 15

the answer is b i just did that

step-by-step explanation:

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.
