<h3>I'll teach you how to solve y^2 - y - 12</h3>

--------------------------------------------------

y^2 - y - 12

Break the expression into groups:

(y^2+3y)+(-4y-12)

Factor out y from y^2+37:

y^2+37 = y(y+3)

Factor out -4 from -4y-12:

-4y-12 = -4(y+3)

y(y+3)-4y-12

Factor out common term y+3:

(y+3)(y-4)

Your Answer Is (y+3)(y-4)

Ira Lisetskai [31]

Answer:

1 or 2

Step-by-step explanation:

1/6 < 1/2 (because 1/2 = 3/6 and 1/6 < 3/6)

2/6 < 1/2 (because 2/6 = 1/3 and if we convert these numbers to decimals, then 0.33 [2/6] < 0.5 [1/2])
