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.
