Helppp and how do did u simply it!!

Answer 1

20
`x^(2)` + 109x -15

Explanation:

12x * 5 = 60x

12x * 3x = 36x

12x * -2x= -24
`x^(2)`

-3 * 5 = -15

-3 * 3x = -9x

-3 * -2x = 6x

2x * 5 = 10x

2x * 3x =6x

2x * -2x= -4
`x^(2)`

60x + 36x -9x + 6x + 10x + 6x = 109x

24
`x^(2)` - 4

-15

Hope this helpss
