The answer is ou need to rewrite the equation to make it easy... and let it equal zero
<span>2<span>x2</span>−8x+4=0</span>
which will become
<span>2(<span>x2</span>−4x+2)=0</span>
you need to solve
<span><span>x2</span>−4x+2=0</span><span>
by completing the square or the general quadratic formula.</span>
