Question

(xy + 3) (xy - 1)
would that be
x^2y^2 + 2xy - 3?

Answer 1

correct

Answer 2

thank you

Answer 3

Anytime

Answer 4

how would i do this..?
(x - 3) (x^2 - 2x + 4) ?

Answer 5

any ideas ?

Answer 6

um

Answer 7

well i was thinking i could do x times 2x and get 2x^2 and then 3 times 4...? im not sure

Answer 8

@sleepyjess can u help?

Answer 9

This is just a longer version of FOIL. Give me just a minute :)

Answer 10

thank you

Answer 11

let me let jess do this she needs 99!!!!!!

Answer 12

(x - 3)(x^2 - 2x + 4)
x*x^2
-3*x^2
now we are done with x^2
x*-2x
-3*-2x
now we are done with -2x
x*4
-3*4
this is all :)

Answer 13

im lost..

Answer 14

out of that i got -3x^2 - 6x^2...? idk

Answer 15

x*x^2 = x^3
-3*x^2 = -3x^2

x*-2x = -2x^2
-3*-2x = 6x

x*4 = 4x
-3*4 = -12

Now put them all together into one equation and combine like terms

Answer 16

x^3 - 5x^2 + 10x - 12 0r....-x^3 - 3x^2 + x - 12?

Answer 17

@sleepyjess

Answer 18

the first one is correct

Answer 19

thx

Answer 20

no problemo :)

Answer 21

would (x+4)(-x^2+x-3) be -x^3-3x^2+x-12?

Answer 22

x*-x^2 = -x^3
4*-x^2 = -4x^2
x*x = x^2
4*x = 4x
x(-3 = -3x 4*-3 = -12
-x^3 - 3x^2 + x -12

Answer 23

yes

Answer 24

okay just one more

Answer 25

okie ^_^

Answer 26

(2x-1)(-x^2-x+4) would that be
2x^3-10x^2-26x-14 or
-2x^3-2x^2+9x-5?

Answer 27

2x*-x^2 = -2x^3
-1*-x^2 = x^2
2x*-x = -2x^2
-1*-x = x
2x*4 = 8x
-1*4 = -8
-2x^3 + x^2 - 2x^2 + x + 8x - 8
-2x^3 - x^2 + 9x - 8

Answer 28

ah, -1*4 does not equal -8, should be -4

Answer 29

yeah im sorry i have answer choices and i looked at them and i typed one of them wrong

Answer 30

i mest up with the 4

Answer 31

so it would be -2x^3 - 2x^2 + 9x - 4?

Answer 32

yes

Answer 33

Thank you so much, you helped me with everything and that means a lot, so thank you :)

Answer 34

no problem! :)
