Z²(z-1)-9(z-1)
= (z²-9)(z-1)
= (z+3)(z-3)(z-1)
Step-by-step explanation:
j=25+5
j=30

I did the math on calculator and got A.
Hope I could help (:
In a graph the roots of the function are given by the cut points with the x axis.
On the other hand, we have the following equation:
y = -x2 - x + 6
To find the roots, we equate to zero:
-x2 - x + 6 = 0
Rewriting we have:
x2 + x - 6 = 0
(x-2) (x + 3) = 0
The roots are:
x1 = 2
x2 = -3
Answer:
The roots are:
x1 = 2
x2 = -3
