Question

Help please, Thank you so much.

Answer 1

(a)
`((1x)/(2) - (1)/(4)) and 5x^2 -2x-6`

To find product ,

first multiply
`((1x)/(2))` with
`5x^2 -2x-6`

`((1x)/(2))* (5x^2 -2x-6) = (5x^3)/(2) - x^2 -3x`

Now multiply
`((-1)/(4))` with
`5x^2 -2x-6`

`((-1)/(4)) * (5x^2 -2x-6) = -(5x^2)/(4) + (x)/(2)  + (3)/(2)`

Now we combine it

`(5x^3)/(2) - x^2 -3x -(5x^2)/(4) + (x)/(2)  + (3)/(2)`

`(5x^3)/(2) - (9x^2)/(4) - (5x)/(2) + (3)/(2)`

(b) No, the products are not same

Because
`((1x)/(2) - (1)/(4)) is interchanged as ((1x)/(4) - (1)/(2))`. when the terms are interchanged then the product will not be same
