Multiply the following polynomials x, (x+3) and (2x-8)

2x^2-2x-24

Step-by-step explanation:

(x+3)*(2x-8)=2x^2-8x+6x-24

                 =2x^2-2x-24     (divide by 2)

                 =x^2-x-12      

hope my answer is right and helpful to u

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to
