Answer:
Factor this polynomial:
F(x)=x^3-x^2-4x+4
Try to find the rational roots. If p/q is a root (p and q having no factors in common), then p must divide 4 and q must divide 1 (the coefficient of x^3).
The rational roots can thuis be +/1, +/2 and +/4. If you insert these values you find that the roots are at
x = 1, x = 2 and x = -2. This means that
x^3-x^2-4x+4 = A(x - 1)(x - 2)(x + 2)
A = 1, as you can see from equation the coefficient of x^3 on both sides.
Typo:
The rational roots can be
+/-1, +/-2 and +/-4

Answer:
Hi I need to get another chance to go back to school subject1
Answer:
8 out of 84: 90% decrease
200 out of 238: 16% decrease
Step-by-step explanation:
To find a percent decrease, you first subtract the end number by the initial number. This gives you the change.
ex. 84-8=76
Now you divide the change by the initial number. You'll get a decimal.
ex. 76/84=0.904...
Multiply the decimal times 100, or move the decimal to the right twice.
ex. 0.904... -> 90.4...
Now round to the nearest ones place
ex. 90.4 -> 90%
Um probably bc ur not asking the correct ones?
