Question 1208683
<br>
Expand (sqrt(x) + 3x)*4 + (sqrt(x) - 3x)*4.<br>
As posted....<br>
{{{(sqrt(x) + 3x)*4 + (sqrt(x) - 3x)*4=(4*sqrt(x)+12x)+(4*sqrt(x)-12x)=8*sqrt(x)}}}<br>
Or perhaps the "4"s were supposed to be exponents?<br>
Use "^" (shift-6) to denote exponentiation.<br>
This problem would have been more interesting:<br>
Expand (sqrt(x) + 3x)^4 + (sqrt(x) - 3x)^4.<br>
If in fact that is what you intended, re-post showing the expression correctly.<br>
