Answer:
Step-by-step explanation:
#This is simple case of addition, who numbers and fractions:
Hence, the summation of this two fractions is 1 3/4
Each of these roots can be expressed as a binomial:
(x+1)=0, which solves to -1
(x-3)=0, which solves to 3
(x-3i)=0 which solves to 3i
(x+3i)=0, which solves to -3i
There are four roots, so our final equation will have x^4 as the least degree
Multiply them together. I'll multiply the i binomials first:
(x-3i)(x+3i) = x²+3ix-3ix-9i²
x²-9i²
x²+9 [since i²=-1]
Now I'll multiply the first two binomials together:
(x+1)(x-3) = x²-3x+x-3
x²-2x-3
Lastly, we'll multiply the two derived terms together:
(x²+9)(x²-2x-3) [from the binomial, I'll distribute the first term, then the second term, and I'll stack them so we can simply add like terms together]
x^4 -2x³-3x²
<u> +9x²-18x-27</u>
x^4-2x³+6x²-18x-27
Answer:
1/6
Step-by-step explanation:
Because there is only a side that has the number 4 in a total of 6 sides
You plug in x = 1 and y = -4 into the system of equations and see if they fit:-
y = -4x
- 4 = -4 * 1 = -4 This fits
y = 2x - 2
-4 = 2*1 - 2 = 0 Does NOT fit.
So (1, -4) is not a solution.
