Step-by-step explanation:
solved in the picture....
Factoring f(x) would give a factor (x-1-2i), so you can divide f(x) by this, leaving (x-3)(x+4)(x-1+2i), so the other roots are:
x=3
x=-4
x=1-2i
Answer:
The person solving the problem first subtracted 6 from 15. Since the cube root is next to the six, the problem should be read as
rather than
.
- To solve it correctly, first find the cube root of -1000/27: <u>-10/3</u>
- Next, multiply by 6: -20
- Finally, subtract from 15: 35
please lmk if anything is wrong with my answer, hope this helps :)
The answer is x^2-2^2
X^2-4
