Let y = 0 to find the zeros.
We can now split the middle term into factors of 6 that add up to 5.
Group the first two terms, and group the last two terms, and factorise.
Group like terms.
Now, we know that in order for a zero to occur, either x + 3 = 0 or x + 2 = 0.
Hence, x = -3 and -2 are the zeros in this quadratic.
