see which one is on the line of the actual equation.

Here we go... hold on to your... plugs...

2 times 1 squared plus 3 times 1 plus 2...

equals 2 plus 3 plus 2, or 7. And a 7, sadly... is not a 10.

1 squared plus 4 times 1 plus 3... equals 1 plus 4 plus 3, which equals 8... so we're

still lookin' for the princess who fits the shoe.

3 times 1 squared plus 4 times 1 plus 4... equals 3 plus 4 plus 4... or 11.

10 isn't even greater than 11, so that doesn't work.

On to D... 2 times 1 squared plus 5 times 1 plus 3... equals 2 plus 5 plus 3... or 10.

Bingo! D should be our answer! Just to check E... 2 times 1 squared plus 5

times 1 plus 6... equals 2 plus 5 plus 6...or 13. Nope.

D it is.

Okay -- you can let go of your plugs now.
