Answer 1

${( frac{ {x}^{2} - x + 2}{2} )}^{2} - 2 times ( frac{ {x}^{2} - x + 2}{2} ) times ( frac{ {x}^{2} - x + 18}{3} ) + {( frac{ {x}^{2} - x + 18 }{3} )}^{2} = 0 \ {( frac{ {x}^{2} - x + 2 }{2} - frac{ {x}^{2} - x + 18 }{3}) }^{2} = 0 \ frac{ {x}^{2} - x + 2 }{2} - frac{ {x}^{2} - x + 18}{3} = 0 \ 3( {x}^{2} - x + 2) - 2( { x }^{2} - x + 18) = 0 \ 3 {x}^{2} - 3x + 6 - 2 {x}^{2} + 2x - 36 = 0 \ {x}^{2} - x - 30 = 0 \ d = {b}^{2} - 4ac = 1 - 4 times 1 times ( - 30) = 1 + 120 = 121 \ x1 = frac{1 + 11}{2} = frac{12}{2} = 6 \ x2 = frac{1 - 11}{2} = frac{ - 10}{2} = - 5$
