I interpreted it 2 procedures. 1st way 5/x + 7 - 3/x - 3 5/x - 3/x = 2/x 7 - 3 = 4 2/x + 4 this may be an answer. or you could combine them further. hit upon a complication-free denominator that's x Numerator = 2 + 4x Denominator = x this could't be simplified 2d way. 5/(x+7) - 3/(x-3) First hit upon a complication-free denominator which would be (x+7)(x-3). Numerator: 5(x-3) - 3(x+7) 5x - 15 - 3x - 21 2x - 36 2(x - 18) Denominator: (x+7)(x - 3) This fraction can not be simplified.

6a(squared) + 3a - 12a(squared) + 20
so 18a(squared) + 3a + 20
