y2-y-72 is an algebraic expression that can be factored as: (y+8)(y-9)
2 - (-9) - 8 = 3
-9(y-9) = -9y+81
It is: 8/9 minus 4/9 = 4/9

10 minus 9/8 is 8 7/8
It is: 8/9 minus 4/9 = 4/9
(9 - y)(a + 5)
8/9 minus 5/9 is 1/3
(3 - i)(3 + i)
9 - 8 = 1
Applying the laws of BODMAS, 9 - 8 + (8 x 5) - 9 = 32
(-9 x -8) + (-16) = (72) -16 = 56
