Hey there!

 

This can be altered using exponential laws like so:

 

\(2^{3x^{2}+2x}=2\)

 

Taking the logarithm of both sides produces the following.

 

\(3x^2+2x=1\)

\(3x^2+2x-1=0\)

 

From this, use the quadratic formula (\(x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}\)), where \(a=3\), \(b=2\), \(c=-1\). This will give you the two \(x\) values you are looking for!

 

Let me know how you get on :)
