Answer:

no real solutions

Explanation:

the easiest method would be to graph the equation and see how many intersection points with the x-axis there are; that represents the number of solutions

when we graph the equation we first want to add 3 to each side of the equation to get the following:

y = 2x²-8x+11

what we see is that the parabola does not intersect the x-axis at all; therefore, there are no 'real' roots or solutions
