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
Step-by-step explanation:
The average is 2. To find the average you add all the numbers then divide the sum by the total amount of numbers.
Answer:
12
Step-by-step explanation:
If Jackie's report is longer than half kane's report, then
Jackie report=1/2 kane's report +5
1/2(14) +5
7+5
=12
therefore, Jackie's report =12
