ANSWERS: 2

subtract 8 to the other side then you have 20 plus/minus √(20squared  4(8)(8) this is all over 2(8) the q formula is as follows: b +/ √(bsquared4ac) _________________________________ 2a

(b +/ sqrt(b^2  4ac))/(2a) 8x^2  20x = 8 8x^2  20x  8 = 0 x = ((20) +/ sqrt((20)^2  4*8*(8))/(2*8) = (20 +/ sqrt(400 (256))/16 = (20 +/ sqrt(656))/16 ~= (20 +/ 25.61249695)/16 = 45.61249695/16 & = 5.61249695/16 ~= 2.850781059 & ~= 0.350781059
