Answer:
14÷2=28
Step-by-step explanation:
Answer: x1=1 x2=-2 and x3=2
Step-by-step explanation:
1st x1=1 is 1 of the roots , so
F(1)=1-1-4+4=0 - true
So lets divide x^3-x^2-4x+4 by (x-x1), i.e (x^3-x^2-4x+4) /(x-1)=(x^2-4)
x^2-4 can be factorized as (x-2)*(x+2)
So x^3-x^2-4x+4=(x-1)*(x^2-4)=(x-1)(x-2)*(x+2)
So there are 3 dofferent roots:
x1=1 x2=-2 and x3=2
The range is {-2, -1, 0, 1, 2}.
Answer:
0.5
Step-by-step explanation:
total tiles = 12
green tiles = 6
so : 6/12 = 0.5
Answer: A. one real solution
This solution is a double root (it repeats itself). An example would be x^2-8x+16 = 0 has the only solution x = 4.
