However, this is a bad answer. You need to zoom way in to see that it is off by one in the second decimal place. The smaller x-value is approximately 1.2449 rather than 1.25, for example

No solutions
2x^2-8x+8=2(x^2-4x+4)=2(x-2)^2
this is not equal at any place to 5(x-2)^2+4
you get 3x^2-12x+16=0
that has a discriminant of -48.
