Factor the trinomial, or state that the trinomial is prime.
y2-9y+14

Please help

Explanation:

To factor this, we need to find two numbers that

Through trial and error, you would find that the two numbers are -2 and -7

-2*(-7) = 14

-2 + (-7) = -9

So that's why the given trinomial factors to (y-2)(y-7)

You can use the FOIL rule to go from (y-2)(y-7) back to y^2-9y+14 again.

answer: 180

step-by-step explanation:

12-2=10

20-2=18

18x10=180
