Question

Factor this please thank you !!

Answer 1

Here's the solution :

`{y}^(2) - 4y+ 45`

`{y}^(2) - 9y - 5y + 45`

`y(y - 9) - 5(y - 9)`

`(y - 5)(y - 9)`

therefore, the roots are 5 and 9

Answer 2

`{y}^(2) - 14y + 45 \\ \\ {y}^(2) - 9 y + 5y - 45 \\ \\ y(y - 9) - 5(y - 9) \\ \\ (y - 5)(y - 9)`
