Associative Operation with Four Vectors: Is it True?

[bgy]

hi,

Is it true that

2*(p+p_1)p_3(p+p_1)p_2 - (p_3)(p_2)(p+p_1)^2 = (p_3)(p_2)(p+p_1)^2 ,

where p,p_1,p_2,p_3 are four vectors? Or simply: associative this operation?

cant quite figure out what u are multiplying by what
why don't u try using latex format
