## FlyinSolo_424 Group Title simplify completely x^2 + 4x - 5 / 5x^2 -8x + 3 ( multiplied ) 20 x - 12 / x^2 - 6x - 55 2 years ago 2 years ago

$\Large \frac{x^{2}+4x-5}{5x^{2}-8x+3}*\frac{20x-12}{x^{2}-6x-55}$ Sidenote: This is what I put into Equation: Large frac{x^{2}+4x-5}{5x^{2}-8x+3}*frac{20x-12}{x^{2}-6x-55}

Ok, so same thing as before: Break down each section of the equation and factor them out.

3. FlyinSolo_424 Group Title

im slowly trying to figure this out . Like I said before Idk Why but im better when There is a variable in there , from when its like this ...

4. FlyinSolo_424 Group Title

I dont think Im Doing this right.

6. Wired Group Title

There is a variable there, X. Step 1: Factor the polynomials. That will help you simplify the equation. $\Large x^{2}+4x-5$ What are the two factors of this? (x- ? )(x+ ? )

7. Wired Group Title

You COULD multiply it all out first, but that would just get confusing quick. Always better to see if there's any factors you can cancel out first before it gets confusing.

8. FlyinSolo_424 Group Title

how about how to simplify the first denominator

9. FlyinSolo_424 Group Title

cause I got for the first numerator (x+5)(x-1) and then Idk how to do the first denominator becasue 8 and 5 dont have anything they can both be divided from. the second numerator 4(x-3) and the second denominator (x-11)(x+5) .. right so far?

10. Wired Group Title

Second Numerator would be 4(5x-3).

11. FlyinSolo_424 Group Title

Crap I need to pay more attention that was.. just me not paying attention -_-

12. FlyinSolo_424 Group Title

First Denominator?

13. FlyinSolo_424 Group Title

I need to hurry got to get off in 10 mins -_- one more question on math

14. Wired Group Title

Quadratic equation for that gets you: (x-1)(5x-3) Quadratic equation: $ax^{2}+bx+c$ $\frac{-b\pm\sqrt{b^{2}-4ac}}{2a}$

15. FlyinSolo_424 Group Title

$4 \div x-11$ is this correct?

16. FlyinSolo_424 Group Title

|dw:1341907059174:dw|

17. Wired Group Title

$\Large \frac{(x+5)(x-1)}{(x-1)(5x-3)}*\frac{4(5x-3)}{(x-11)(x+5)} = \frac{1}{1}*\frac{4}{(x-11)}$ Yep.

18. FlyinSolo_424 Group Title

;D thank you. so much ! and now I know to use the quadratic formula if I cant simplify like that. Thank you :D

19. Wired Group Title

No problem at all. Have you covered the quadratic equation yet?
