Question

help and will medal.. Why can't I get to any of the answer?

Answer 1

@iGreen

Answer 2

Do we flip the 2nd fraction and cross multiply? xD

Answer 3

When dividing flip the second fraction and multiply, this requires factoring, it will look nice eventually, so what have you tried?

Answer 4

It's more so to test if you can factor

Answer 5

\[\frac{ (x-3)(x-4) }{ (X-5)(x-4) } \div \frac{ 3(x-5)(x-3) }{ 12(x+1)(x-5) }\]

Answer 6

is it correct? Any mistake?

Answer 7

Mhm not quite, I see some of your factors are wrong \[x^2+x-12 \implies (x+4)(x-3)\]
\[(x^2-x-12) \implies (x+4)(x-5)\]

Answer 8

\[3x^2-24x+45 \implies 3(x-3)(x-5)\] so I see you got this one right

Answer 9

Your last one looks good to

Answer 10

So your first two factoring were wrong

Answer 11

\[\frac{ (x+4)(x-3) }{ (x+4)(x-5) } \times \frac{ 12(x+1)(x-5) }{ 3(x-5)(x-3) }\] cancel away

Answer 12

ok so i got 4(x+1) / x-5 when i cross it out

Answer 13

Yeah, that sounds good to me!

Answer 14

THnaks Batman you're my hero

Answer 15

Np :)
