Question

Factor completely 3x^4 - 30x^3 + 75x^2

3(x-5)^2
3x^2(x-5)^2
3x^2(x^2-10x+25)
3x^2(x+5)(x-5)​

Answer 1

The answer to your question is: 3x² (x - 5) ²

Explanation:

Factor like terms 3x⁴ - 30x³ + 75x²

3x² ( x² - 10x + 25)

Factor ( x² - 10x + 25) = ( x - 5) (x - 5) = (x - 5) ²

Finally 3x² (x - 5) ²
