Question

25y²-90y+81
Factor the polynomial completely

Answer 1

The answer is

`{(5y - 9)}^(2)`

Explanation:

factor

`{(25y }^(2) - 90y + 81)`

get the GCF of 25,-90,81=1

get the square root of leading terms

`\sqrt{25 {y }^(2) } = 5y \: and \: √(81) = 9`

the final answer is

`{(5y -9) }^(2)`
