Start by moving everything to one side so you get a standard form equation which equals to 0.

which would be x² -2x-46=0

Then you can complete the square or use the quadratic formula to solve for x

the standard form is ax²+bx+c=0 and the quadratic formula is 

so just plug in all the values to get \(x = {1 \pm \sqrt{47}}\)

Hi Melody, I tried the question by my self and got -2(x-2)^2 +18. I got this from -1/2(4)x^2+8x+10 and after I solved that I got what I first said.
