Question 1031366
<pre><b>
Line the like terms up in columns like this and then
just add the terms:

       f(x) =         x³ + 3x² + 4x -  7
       <u>g(x) = -7x&#8308; + 5x³ +  x²      -  7</u>
f(x) + g(x) = -7x&#8308; + 6x³ + 4x² + 4x - 14 

</pre>  
What is the coefficient of x^3 in the sum f(x) + g(x)?
<pre>
Look and see.
