( a + b )"' - ( a + b )
= ( a + b )[ ( a + b )" - 1 ]
= ( a + b )[ ( a + b )" - 1" ]
= ( a + b )( a + b + 1 )( a + b - 1 )
a"( x - y )" - b"( y - x )"
= [ a( x - y ) ]" - [ b( x - y ) ]"
= [ ( ax - ay ) + ( bx - by ) ][ ( ax - ay ) - ( bx - by ) ]
= ( ax - ay + bx - by )( ax - ay - bx + by )

Factorization of a-tripartite + b-tripartite + c-tripartite-3abc


a^3+b^3+c^3-3abc
=(a+b)^3-3ab(a+b)+c^3-3abc
=(a+b)^3+c^3-3ab(a+b)-3abc
=(a+b+c)^3-3(a+b)*c*(a+bc)-3ab(a+b+c)
=(a+b+c)*[(a+b+c)^2-3ab]
=(a+b+c)(a^2+b^2+c^2-ab-ac-bc)
Next, expand and merge similar items = (a-b + B-C) ^ 3 + 3 (a-b) (B-C) (a-b + B-C) + (C-A) ^ 3
=(a-c)^3+3(a-b)(b-c)(a-c)-(a-c)^3
=3(a-b)(b-c)(a-c)



Can (a + b) (a-b) be factorized~~~~~~~~~~~~~~~~~~~~~~~~~


Did you learn the radical? Did you learn the plural?
In the range of real numbers, only when a and B are not negative can we continue to decompose (we can decompose them all the time), but only in specific problems. Otherwise, what we have now is the most concise;
In the complex number range, of course, it can be decomposed, because I & sup2; = - 1, it can still be decomposed all the time, and it can only be decomposed in specific problems
