Question

Simplify x/2*x² – 2x – 24/4*8/x +4

Answer 1

`(x)/(2) . \frac{ {x}^(2) - 2x - 24 }{4} . (8)/(x + 4)`

`= (x)/(2) . \frac{ {x}^(2) - 6x + 4x - 24x }{4} . (8)/(x + 4)`

`= (x)/(2) . (x(x - 6) + 4(x - 6))/(4) . (8)/(x + 4)`

`= (x)/(2) . ((x - 6)(x + 4))/(4) . (8)/(x + 4)`

`= x(x - 6)`

`= {x}^(2) - 6x`
