Final answer:
To factor the polynomial completely, we can use various methods such as factoring by grouping, synthetic division, or using the rational root theorem. For the given polynomial, x⁴ - 5x³ + x² + 25x - 30, factoring by grouping yields x(x - 5)(x² + 25) - 30 as the complete factorization.
Step-by-step explanation:
To factor the polynomial completely, we can use various methods such as factoring by grouping, synthetic division, or using the rational root theorem. Considering the given polynomial, x⁴ - 5x³ + x² + 25x - 30, we can try factoring it by grouping.
Grouping terms, we have: (x⁴ - 5x³) + (x² + 25x) - 30.
Factoring each group further, we get x³(x - 5) + x(x + 25) - 30.
Now, we can factor out common terms and simplify further: x³(x - 5) + x(x + 25) - 30 = x(x - 5)(x² + 25) - 30.
So, the polynomial x⁴ - 5x³ + x² + 25x - 30 can be completely factored as x(x - 5)(x² + 25) - 30.
