Question

Simplify the rational expression.
(5b^3 − 4b^2 − 7b)/(4b^2)

I have tried working it out and got
(5x^2-4x-7)/(4x)
But this is not the correct answer

Answer 1

I've also gotten (b (5 b-4)-7) / (4b).... this is also incorrect

Answer 2

(5x^2-4x-7)/(4x) is correct...
maybe u want to use b as the variable instead of x ???
