Question

If x = -1, then (x - 1)(2 - x) = ?

Answer 1

Answer= -9

Ok so if x equals -1 we just plug in -1 where we see x
The equation after we plug in -1 for x would look like
(-1-2)(2-(-1))

Then we would solve
-1-2 is -3
(-3)(2-(-1))
2-(-1) is 3
Which leaves us with -3(3)
Which equals -9 :)

Answer 2

Answer=-6
(-1-1)=-2
(2-(-1))=3
-2*3=-6
