Someone help me with this math problem...

[GreecePwns]

I need to know this by tommorrow (my teacher was absolutely no help at all, which means no one in my class knows). Here's an example:

Factor completely

(9x^[2y+2]) - (27x^2y)

Winner gets...i don't know...a cookie or something. Maybe a 1v1 when I get a free space.

[Norse]

Bracket it more clearly...

[Dancing Mustard]

7.5

Easy, now give me a biscuit for being a genius.

[wicked]

is 2K = 2000 or is K another variable?

[GreecePwns]

is 2K = 2000 or is K another variable?

another variable

I need to know this by tommorrow (my teacher was absolutely no help at all, which means no one in my class knows). Here's an example:

Factor completely

(9x^2k+2) - (27x^2k)

Winner gets...i don't know...a cookie or something. Maybe a 1v1 when I get a free space.

dude, bracket the powers more clearly...is it 9x to the power of 2k+2..or 9x to the power of 2 multiplied by k+2?

[0ojakeo0]

what grade are you in?

[wicked]

Well all I could do with it is ...

x^2k = 1/9

assuming it's really (9x^2k)+2 - 27x^2k ???


But I don't really remember what "factor completely" means.

[GreecePwns]

what grade are you in?

In American terms, 10th.

factorise

[0ojakeo0]

what grade are you in?

In American terms, 10th.

Ok dont got to worry for two more years.

[Norse]

you done logrythyms yet?

[GreecePwns]

Ok dont got to worry for two more years.

But it's Honors level work so, i guess you can say 11th or 10 1/2th

[GreecePwns]

you done logrythyms yet?

nope.

[Norse]

hehe, well I hope you're a fast learner...

[GreecePwns]

hehe, well I hope you're a fast learner...

somewhat...but the point is i could've done it if the +2 in the first term's exponent using GCF.

Ill probaly be in honors though...

[nagerous]

have you rationalised the denominator?

[Dancing Mustard]

Have you calibrated the optimal value for the first variable? That ought to be your first step.

[GreecePwns]

have you rationalised the denominator?

There's no denominator?

Have you calibrated the optimal value for the first variable? That ought to be your first step.

Factor completely

(9x^[2y+2]) - (27x^2y)

Winner gets...i don't know...a cookie or something. Maybe a 1v1 when I get a free space.

9x^(2y)*(x-sqrt(3))(x+sqrt(3))

[Norse]

9X Log (2y + 2) = 27X Log (2y)

1/3 log(2y + 2) = Log (2y)

Factor completely

(9x^[2y+2]) - (27x^2y)

Winner gets...i don't know...a cookie or something. Maybe a 1v1 when I get a free space.

Damn thats easy.

9x^2y(x^2-3x)

Remember, when you times polynomials you times the base, and add teh powers.

9x^2y times x^2 = 9x^(2y+2)

9x^2y times -3x = -(27x^2y) [Remember, -3x is actually -3x^1]

Additional: You can write (9x^2y)(x^2-3x) if you want, but thats unnecessary because the first bracket is all 1 product.

You're subtracting them, not multiplying.

You're subtracting them, not multiplying.

No I'm not. When expanding the bracket, you do not subtract first. You times the first product by the outside product, and then you times the second product (with the negative sign) by the outside product.

Its impossible to simplify a subtraction which involves polynomials of different powers.
