2015年5月23日 · Using the identity #a^3+b^3 = (a+b)(a^2-ab+b^2)# we find: #64x^3+27 = (4x)^3 + 3^3# #= (4x+3)((4x)^2-(4x)*3+3^2)#

2018年5月3日 · (4x+y)(16x^2-4xy+y^2) This is an example of factoring perfect cubes. 64x^3+y^3 64 is a perfect cube 4*4*4 x^3 is a perfect cube x*x*x y^3 is a perfect cube y*y*y The factor pattern for factoring perfect cubes is always (a+b)(a^2-ab+b^2) or (a-b)(a^2+ab+b^2) The signs follow the acronym SOAP First sign is the SAME as the expression Second sign is the …

2016年4月30日 · This expression is a #color(blue)" sum of cubes "" and is factorised as follows " #. #color(red)(|bar(ul(color(white)(a/a)color(black)( a^3 + b^3 = (a + b)(a^2 -ab +b ...

2017年10月31日 · Note that #64x^3 = (4x)^3# and #343 = 7^3# are both perfect cubes and:. #a^3+b^3 = (a+b)(a^2-ab+b^2)# So putting #a=4x# and #b=7# we find:

2015年4月22日 · #64x^3+1# # = (4x)^3 + 1^3# We know that #color(blue)(a^3 + b^3 = (a+b)(a^2 - ab + b^2)# # = (4x + 1)((4x)^2 -(4x)(1) + 1^2)#
