Question

5x+6/x2+2xALL OVERx−4/x2+2x
need help simplifying

Answer 1

You can't finish the last step from the previous problem?

\[\frac{a}{b} \div \frac{b}{c} = \frac{a}{b} \times \frac{b}{c} = \frac{a}{c}\]

Answer 2

so i dont understand still?

Answer 3

from @Hero equation a=5x+6 and b=x^2+2x. your c=x-4 and d=x^2+2x

Answer 4

b=d are the same in this case

Answer 5

you get the answer?

Answer 6

no

Answer 7

Same -> change - flip
Treat the large fraction as a division problem.
The numerator will be the first fraction, the denominator will be the second fraction.
Keep the first fraction the same
change the division to multiplication
flip the second fraction (reciprocal)

Answer 8

A slight adjustment to Hero's equation to correct a minor mistake.
\[\frac{a}{b} \div \frac{c}{b} = \frac{a}{b} \times \frac{b}{c} = \frac{a}{c}\]

Answer 9

do i cross multiply or direct multiply

Answer 10

First you see if you can cancel. When multiplying fractions, you can cancel any numerator with any equal denominator.

Answer 11

Then you multiply straight across.

Answer 12

do the x^2 + 2x's cancel?

Answer 13

yes they do.

Answer 14

5x + 6 over x - 4?

Answer 15

awesome thank you!

Answer 16

You got it!
Sorry I couldn't add that last bit to your last question, I kept getting booted off.
