284.13 grams
because you do 4.51 x 21 , then you have to multiply by 3
First we distribute
into
and
.
That makes the left side of the equation
Now we subtract
from
, which makes
Now the equation is
Our goal is to isolate
, so we both sides by 30
That will make the equation
We multiply -1 on both sides of the equation:
Finally we simplify
, which makes
So the answer is
______
-2±_/4-4(2)(3)
-------------------
2(2)
The answer is 20x^2 + 14x + 2
