Question

Ignore the circled one and actually try please​

Answer 1

a.
`(x^3-4x^2)/(3x+15)`

Explanation:

`\huge{ (2x^4)/(x+5) / (6x^2)/(x-4) }\\\\\huge{= (2x^4)/(x+5) * (x-4)/(6x^2)}\\\\\huge{ =(x^2)/(x+5) * (x-4)/(3)}\\\\\huge {=(x^2(x-4))/(3(x+5))}\\\\\huge{=(x^3-4x^2)/(3x+15)}`

Answer 2

A

Explanation:

= 2x5−8x4 /(6x3+30x2)

= 2x3−8x2 /(6x+30 )

= x3−4x2 /(3x+15)
