Given that u =Home workandfind4 - 2(2) and6b (u + x)3
1 answer:
Answer:
u³ + 2u²x + x²u + xu² ´+ 2ux² + x³
Explanation:
(4-2)² = 2² = 4
(u+x)³ = (u+x) * (u+x)²
= (u+x) * {(u+x)(u+x)} = (u+x)*{u*u + u*x + x*u + x*x}
= (u+x)+{u²+2ux+x²} = u*u² + u*2ux + u*x² + x*u² + x*2ux + x*x²
= u³ + 2u²x + x²u + xu² ´+ 2ux² + x³
