Question

Simplify completely (x^2+x-12)/(x^2-x-20)÷(3x^2-24+45)/(12x^2-48x-60)

Answer 1

i got 4(x+1)/(x-5)?

Answer 2

help?

Answer 3

(x^(2)+x-12)/(x^(2)-x-20){(3x^(2)-24+45)/(12x^(2)-48x-60)

((x+4)(x-3))/(x^(2)-x-20)*(12x^(2)-48x-60)/(3x^(2)-24+45)

((x+4)(x-3))/((x+4)(x-5))*(12x^(2)-48x-60)/(3x^(2)-24+45)

(x-3)/(x-5)*(12x^(2)-48x-60)/(3x^(2)-24+45)

(x-3)/(x-5) * (12x^(2)-48x-60)/(3x^(2)+21)

(x-3)/(x-5) * (12(x^(2)-4x-5))/(3x^(2)+21)

(x-3)/(x-5) * (12(x+1)(x-5))/(3x^(2)+21)

(x-3)/(x-5) * 12(x+1)(x-5))/(3(x^(2)+7))

(x-3)/(x-5) * 4(x+1)(x-5)/(x^(2)+7)

(x-3) * 4(x+1)/(x^(2)+7)

4(x-3)(x+1)/(x^(2)+7)

Answer 4

its multiple choice
A- (x-5)/4(x+1)
B- (x+1)/8(x-5)
C-4(x+1)/(x-5)
D-8(x-5)/(x+1)

Answer 5

I'm sorry. It's You're correct. It's C

Answer 6

(: what about this one

Answer 7

(x^2-4x+4)/(x^2+10x+25) * (x+5)/(x^2+3x-10)

Answer 8

(x-2)/(x+5)^2

Answer 9

x-2/(x+5)^2

Answer 10

(x^2-100)/(x^2+2x-120) ÷ (6x+60)/(x-2)?

Answer 11

o.0 i dont understand how you can do it this fast

Answer 12

sorry, x+10/x+12

Answer 13

x^2-100 = (x+10)(x-10)
x^2+2x-120= (x+12)(x-10) ~~ I have a trick to get this fast

Answer 14

Multiple choice again
x-1/6(x+6)
x-2/6(x+10)
x-2/6(x+12)
x-1/3(x+12)

Answer 15

Oh, Ok. Sorry. I only did the first part.

Answer 16

x-2/6(x+12)

Answer 17

one more question
(x^2+4x-5)/5x^2-8x+3) * (20x-12)/x^2-6x-55)
A) 4/x+5
B)4(x-1)/x+5
C) 4/x-11
D)4(x+5)/x-11

Answer 18

C) 4/x-11

Answer 19

Hope you got it :)

Answer 20

Thank you so much for all your help I'm sure ill be back haha
