Question

The HCF of 20x⁵-38x⁴+43x³-25x² and 15x⁵-19x⁴+4x³ is:​

Answer 1

Answer:

Step-by-step explanation:

Factors of 20x⁵ - 38x⁴ + 43x³ - 25x²

= 2 × 2 × 5 × x² × x³ - 2 × 19 × x² × x² + 43 × x² × x - 5 × 5 × x²

Factors of 15x⁵ - 19x⁴ + 4x³

= 3 × 5 × x² × x³ - 19 × x² × x² + 2 × 2 × x² × x

∴ HCF = 2 × 2 × 5 × 19 × x² × x = 380x³ is the answer
