Simplify the expression below and explain your steps. x/2=x/8

x2-x-8=0

Step-by-step explanation:

The first term is,  x2  its coefficient is  1 .

The middle term is,  -x  its coefficient is  -1 .

The last term, "the constant", is  -8  

Step-1 : Multiply the coefficient of the first term by the constant   1 • -8 = -8  

Step-2 : Find two factors of  -8  whose sum equals the coefficient of the middle term, which is   -1 .

     -8    +    1    =    -7  

     -4    +    2    =    -2  

     -2    +    4    =    2  

     -1    +    8    =    7
