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

Mathematics
1 answer:
Nat2105 [25]1 year ago
8 0

Answer:

(x-y)(x-y)(x-y)= x²-yx+x²-yx-yx+y²-yx+y²

2x²-4yx+2y²

(y-x)(y-x)= y²-yx-yx+x²

y²-2yx+x²

-(y²-2yx+x²) = -y²+2yx-x²

2x²-4yx+2y²-y²+2yx-x²= x²-2yx+y²

or

(x−y−1)(x−y)² ≡ x³−x²+3xy²+2xy−y³−y²−3yx³

Cameron's uncle is 3 times old as he is. 4 years ago, he was 4 times older. How old is Cameron?
erma4kov [3.2K]

Let Cameron be x years old now.

-

<u>Now:</u>

Cameron = x

Uncle =3x

-

<u>4 years ago:</u>

Cameron = x - 4

Uncle = 3x - 4

-

<u>4 years ago, Uncle is 4 times older:</u>

3x - 4 = 4(x - 4)

-

<u>Find x:</u>

3x - 4 = 4(x - 4)

3x - 4 = 4x - 16

4x - 3x = 16 - 4

x = 12

-

<u>Find the age:</u>

Cameron = x = 12

-

Answer: Cameron is 12 years old now.
