- expand the polynomials - (x^(2)+xy-y^(2))(x+y)

(b-c)(b^2-bc-c^2)

(a^2-2a+3)(a-4)

(5x-2)(x^2-x-1)

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

the answer is stop cheating on things stoopid
