Calculate [(A-1) square - (1 + a) square] / (- 2A) [(A-1) - (1 + a)] / (- 2A) calculation
[(a-1)-(1+a)]/(-2a) =[(a-2a+1)-(a+2a+1)]/(-2a) =(-4a)/(-2a) =2
The specified operation # is as follows: when a > b, a # B = a times the square of B-1, when a = B, a # B = 2a-1, when a = B, a # B = 2a-1, when a
When x
Calculate (a + 2) (a square - 2A + 4) - (A-1) (a square + A + 1)
(a + 2) (a square - 2A + 4) - (A-1) (a square + A + 1) = 9
