 Answer:
1. x²-2x+15 
This can't be factored, I've tried multiple ways now, but it just can't be factored. 
2. y²-19y+90
Let's factor y^2−19y+90
y^2−19y+90
The middle number is -19 and the last number is 90.
Factoring means we want something like
(y+_)(y+_)
Which numbers go in the blanks?
We need two numbers that...
    Add together to get -19
    Multiply together to get 90
Can you think of the two numbers?
Try -9 and -10:
    -9+-10 = -19
    -9*-10 = 90
Fill in the blanks in
(y+_)(y+_)
with -9 and -10 to get...
(y-9)(y-10)
Answer:
(y−9) (y−10)
