Question

How do you simplify the following equation:
(2x^2-5)-(x+7)(4x)
----------------
(2x^2-5)^2

Answer 1

multiply out in the numerator using the distributive property and then combine like terms

Answer 2

\[2x^2-5-4x^2-28x\]
\[=-2x^2-28x-5\]

Answer 3

so answer is
\[\frac{-2x^2-28x-5}{(2x^2-5)^2}\]

Answer 4

nothing cancels if you have written the numerator correctly.

Answer 5

Yeah~ that's what I got also it just looked odd because I thought it could be simplified more, but I guess not! Thank you!
