Question

Evaluate: xy - x (x - y^0) if x = 2 and y = -1/2

Answer 1

`2(- (1)/(2) ) - 2(2+(- (1)/(2))^0)`


`- (2)/(2) - 2(2+(- (1)/(2) )^0)`


`-1 - 2(2+(- (1)/(2) )^0)`


`-1 -2 (2+1)`


`-1 -2*(3)`-1 -2(3)


`-1 -6`


`-7`

Answer 2

Hi

2(-1/2) - 2(2+(-1/2)^0)
= -2/2 - 2(2+(-1/2)^0)
= -1 - 2(2+(-1/2)^0)
= -1 -2 (2+1)
= -1 -2(3)
= -1 -6
= -7

I hope that's help :)
