Question 438036
<font face="Times New Roman" size="+2">


No, absolutely not.  There are two very compelling reasons, one general and the other specific, why not.


First, in general, when you are asked to solve for *[tex \Large x], you have to solve for *[tex \Large x], not *[tex \Large x^2] or anything else.


Second, specifically for this problem, *[tex \Large x^2\ \neq\ 69.7].  Not even close.


Start over.  Take the square root of both sides.  Remember to consider both the positive and negative roots.  Set 3x + 7 equal to the positive root and solve.  Then set 3x + 7 equal to the negative root and solve.  Since 676 is a perfect square, x will be a rational number.
