This is known as "5 take 3", where ordering is not important.

It should be #4. or d to clarify
So you need to turn 5x^2 -3x -9 into 2x - 3.
Well first you need to take 5x^2 out by subtracting 5x^2 (-5x^2).
Then -3x needs to become 2x by adding 5x (+5x).
Finally -9 needs to become -3 by adding 6 (+6).
Put all the things you did together to make a polynomial.
-5x^2 + 5x + 6
1.2 .10/2=120.0( standard form)
because the exponent of the 10s term is positive we must move the decimal point 2 places to the right.
