please help factor completly 3a^4b+3ab^4
ans.
given 3a^4b+3ab^4
= 3ab(a^3+b^3)
= 3ab(a+b)(a^2-ab+b^2)
since x^3+y^3=(x+y)(x^2-xy+y^2)

factor completly 3a%5E4b%2B3ab%5E4
First factor out the GCF (greatest common factor):
3ab%2Aa%5E3%2B3ab%2Ab%5E3
3ab%28a%5E3%2Bb%5E3%29
The sum of cubes is factored by the formula: highlight%28u%5E3%2Bv%5E3=%28u%2Bv%29%28u%5E2-uv%2Bv%5E2%29%29
3ab%28a%2Bb%29%28a%5E2-ab%2Bb%5E2%29
Happy Calculating!!!
