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

Answer:

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

Step-by-step 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
