Show that (a - b)+(b-c)+(c -a)3 = 3 (a - b) (b -c) (c-a)​
nikdorinn [45]

Answer:

I think that it should be

{(a - b)}^{3}  +  {(b - c)}^{3}  +  {(c - a)}^{3}  = 3(a - b)(b - c)(c - a)

Step-by-step explanation:

Here,

we take , a - b = A,b-c = B , c - a= C

A+B+C = 0

we know that,

{a}^{3}  +  {b}^{3}  +  {c}^{3}   - 3abc = (a + b + c)(  {a}^{2}  +  {b}^{2}  +  {c}^{2}  - ab - bc - ca)

Here , A+B+C = 0

so,

A^3 +B^3 + C^3 = 3 ABC

now we put the values

{(a - b)}^{3}  +  {(b - c)}^{3}  +  {(c - a)}^{3}  = 3(a - b)(b - c)(c - a)

I am done .

I'm not sure to do this.. Help me please.. Thank you
Paraphin [41]
So our original equations would be..
2y + 2(y - 4) = p \: (perimeter)
y \times (y - 4) = l \: (area)

(a) perimeter in terms of y
y = \frac{p + 8}{4}

(b) area in terms of y
*I'm actually not sure about b.. sorry*

(c) if perimeter = 28, find length
28 \div 4 = 7
7 \times 7 = 49
l (area)= 49
