Very close. What is 1 times 1?

Right! So your equation would be 3x  5  5x  1. Can you combine the like terms?

Lets rearrange it so its easier to work with. Remember to keep the symbol in front of each term. 3x  5x  5  1 First off, what is 3x  5x?

\[(5x^2 + 3x + 4)  (2x^2 + 5x  1)\]We have to distribute the 1. \[(1)\stackrel{\Huge\curvearrowright}(2x^2 + 5x  1)\]1 * 2x^1 = 2x^2 1 * 5x = 5x 1 * 1 = 1 Now we have: \[5x^2 + 3x + 4  2x^2  5x + 1\]Combine like terms. 5x^2  2x^2 = 3x^2 3x  5x = 2x 4 + 1 = 5 And we end up with: \[\large 3x^2  2x + 5\]

\[\large Ax^2 + Bx + C\] \[\large 3x^2  2x + 5 \] So what is A?
