Given -
x³ + 4x² + 8x + 32
To Find -
Factor completely =?
Step-by-Step Explanation -
x³ + 4x² + 8x + 32 can be written as:
= (x³ + 4x²) + 8x + 32
= x²(x + 4) + 8(x + 4)
Now it can be written as:
(x² +8)(x + 4)
So, the complete factor of x³ + 4x² + 8x + 32 is (x + 4)(x² + 8)
Final Answer -
A. (x+4)(x² + 8)
