Question 1019621

1. Solve sqrt2x + x = 4 for x.
Answers: A. x = 2   B. The two solutions are for complex numbers.  
C. x = 2 or x = 8 ( I picked C and it was wrong) D. x = 4 or x = -4

Thank You.
<pre>This appears to be {{{sqrt(2x) + x = 4}}}. If so, the answer CANNOT be C, but: {{{highlight(highlight_green(highlight(matrix(1,2,CHOICE, A))))}}}, instead.
Why don't you use parentheses, or provide info to make this problem less ambiguous? Is that so difficult?
