Answer:
p = x² − 6x + 10
Step-by-step explanation:
Complex roots come in conjugate pairs. So if 3−i is a root, then 3+i is also a root.
p = (x − (3−i)) (x − (3+i))
p = x² − (3+i)x − (3−i)x + (3−i)(3+i)
p = x² − 3x − ix − 3x + ix + (9 − i²)
p = x² − 6x + 10
You can check your answer using the quadratic formula.
x = [ -b ± √(b² − 4ac) ] / 2a
x = [ 6 ± √(36 − 40) ] / 2
x = (6 ± 2i) / 2
x = 3 ± i
Answer:
2,-2

Because you move left and gou up 4
Exactly the way you do it with numbers:
-- List all the factors of the first one.
-- List all the factors of the second one.
-- List all the factors of the third one.
-- Make a short list, consisting of the factors that appear
on all three lists. Those are the 'common' factors.
-- The greatest item on the short list is the greatest common factor.
14m², 27a³, and 45a² don't have any common factor except ' 1 '.
Since ' 1 ' is their only common factor, it's also their greatest one.
Equivalent fractions are different fractions that name the same number. Equivalent fractions may look different, but they have the same value.
