So since -2, 0, 1 are the roots:
Therefore x = -2, x = 0 , x = 1
Implies that:
x = 2 x - 2 = 0
x = 0 x = 0
x = 1 x - 1 = 0
Therefore (x - 2)x(x - 1) = 0
(x - 2)(x - 1) = x(x - 1) - 2(x - 1) = x² - x - 2x + 2 = x² - 3x + 2
(x - 2)x(x - 1) = 0
(x - 2)(x - 1)x = 0
(x² - 3x + 2)x = 0
x*x² - x*3x + x*2 = 0
x³ - 3x² + 2x = 0
This is the polynomial with the least degree, because it possible for another polynomial with higher power to still have the same root.
x³ - 3x² + 2x = 0 is the polynomial.
I hope this helps.
Answer:
1.5 cups of raisins were needed.
Step-by-step explanation:
I am going to solve this question using a rule of three.
The cookie recipe called for raisins and nuts in the ratio of 3 to 2.
This means that for three cups of raisins, two cups of nuts are needed.
If one cup of nuts was called for how many cups of raisins were needed?
3 cups of raisins - 2 cups of nuts
x cups of raising - 1 cup of nuts
1.5 cups of raisins were needed.
-1.....if the number on the left is smaller than the number on the right change the the number on the right to equal the same on the left then however many numbers down you went make that a negative and that’s your answer
Answer:
-459 2/9
Step-by-step explanation:
calculate 34-99= -65
and turn 2 7/9 into a mixed number as 25/9
leaves u with
7(-65)-7+25/9
multiply 7x-65=-455
-455-7+25/9
-462+25/9
get common denomionator and add
-4133/9 or -459 2/9 or -459.2
Answer:
y = 9x-8
Step-by-step explanation:
Find y values for x= -3 and x = 3. These will come out to -35 and 19 respectively.
Plug these numbers into the rise/run equation for slope m (y2-y1)/ (x2-x1). Plugging values in and simplifying you will get 54/6, which reduces to 9. This is your m value.
Apply your m value to x = 3 going backwards (x = 2 gives a y value of 10, 1 gives 1, and 0 gives -8). This will give you a y intercept of -8. This is your b value.
Plug the slope and y intercept into the mx + b equation. This will give you y = 9x-8.
There you go!
