Answer:
x^3+5x^2 + 10x + 12
Step-by-step explanation:
Multiply each term in the first expression by each term in the second expression and combine like terms.
Thus, the answer is x^3 + 5x^2 + 10x + 12
Answer:
x³ + 5x² + 10x + 12
Step-by-step explanation:
( x + 3 ) ( x² + 2x + 4 )
= [x ( x )² + x ( 2x ) + x ( 4 )] + [3 ( x² ) + 3 ( 2x ) + 3 ( 4 )]
= x³ + 2x² + 4x + 3x² + 6x + 12
= x³ + 2x² + 3x² + 4x + 6x + 12
= x³ + 5x² + 10x + 12
Hence, simplified.
Standard form of ( x + 3 ) ( x² + 2x + 4 ) is x³ + 5x² + 10x + 12.
