The sum of the roots = -7/6
The product of the roots is -2/18
Therefore the quadratic equation is
18x^2 + 21x - 2
You are adding 2 each time.
4 terms are given to you, with 5th term being 2
20 - 5 = 15
Multiply 15 with 2
15 x 2 = 30
Add the number gotten with the last number given
30 + 2 = 32
32, or (A) is your answer
hope this helps
Step 1-F.O.I.L.: (-2-2i)(-4-3i)
8+6i+8i+3i^2
We know i^2=-1, so...
8+14i-3
5+14i
Step 2-F.O.I.L. again: (5+14i)(7+8i)
35+40i+98i+112i^2
35+138i-112
-77+138i
Note: "F.O.I.L." stands for "First, Outer, Inner, Last". In other words, distribute the terms of the first binomial to the other, in that order. So, (5+14i)(7+8i) should be done as follows:
5*7=56
5*8i=40i
14i*7=98i
14i*8i=112i^2
