Answer:
x=2, x=-1
Step-by-step explanation:
f(x) = x^2 − x − 2
Set equal to zero
0 = x^2 − x − 2
Factor
What 2 numbers multiply to -2 and add to -1
-2*1 = -2
-2+1 =1
0=(x-2) (x+1)
Using the zero product property
x-2 =0 x+1 =0
x=2 x=-1
Let L, W and P denote length, width and perimeter.
L = (2/3)W - 5
The perimeter, P, is 2W + 2L, and this, in turn, is
2W + 2((2/3)W - 5), or 2W + (4/3)W - 10, or
(2 + 4/3)W - 10, or (10/3)W - 10
