Question

Factor completely 3x4 – 30x³ +75x². (1 point)

O3(x - 5)²
3x²(x - 5)²
3x²(x²-10x+25)
3x²(x + 5)(x - 5)

Answer 1

Answer: 3x²(x - 5)²

Explanation:

Factoring out 3x² of each term leaves you with 3x²(x² - 10x +25)

We can still factor out (x² - 10x +25) to (x-5)(x-5), which is simply (x-5)².

This will leave you with 3x²(x - 5)².
