1 3/4 x 2/4 = ( 1 + 3/4 ) x 2/4 = ( 4/4 + 3/4 ) x 2/4 = 7/4 x 2/4 = 7x2/ 4x4 = 14 / 16 Answer A By the way: 14 / 16 = 2 • 7 / 2 • 8 = 7 / 8
Multiply all terms by (x-2)(x+1) x(x+1)+(x−1)(x−2) = 1(x−2)(x+1) 2x^2−2x+2 = x^2−x−2 Subtract x^2-x-2 from both sides 2x^2−2x+2−(x^2−x−2) = x^2−x−2−(x^2−x−2) x^2−x+4 = 0 The solutions are: x = ( 1 ± i √15 ) / 2
