Question

Expand & simplify:
(x - 3)(x-4)

Answer 1

x

`{x}^(2) - 7x + 12`

Explanation:

`(x - 3)(x - 4)`

`x( x - 4) - 3(x - 4)`

`{x}^(2) - 4x - 3x + 12`

`{x}^(2) - 7x + 12`

Answer 2

`{x}^(2) −7x+12`

Explanation:

`(x−3)(x−4)`

`x(x−4)−3(x−4)`

`x * x+x(−4)−3x−3(−4)`

`{x}^(2) −4x−3x+12`

`{x}^(2) −7x+12`
