Factoring polynomials by grouping is easy. You just combine like terms and then factor them out. Ta da!

The area of the hovel floor should be x2 + 3x + 2x + 6.
All those polynomials are making Grunkle rather blue.
Which is unfortunate, since Grunkle is usually a lovely emerald green.
Good thing we can factor this polynomial by grouping.
The first two terms have a common factor of x
and the last two terms have a common factor of 2.
We can rewrite the polynomial as x times x + 3 + 2 times x + 3.
See another factor we can pull out?
Since both terms have x plus 3 as a factor, we can pull out an x plus 3 from each.
This gives us (x + 2) times (x + 3).
Happy factorization, Grunkle!
All you have to do now is look at your blueprint to see what x is.
And x equals... the length of a ferocious jungle jabberwocky.
Sorry, you're on your own.
