Answer:
-5+√3i is the given root so -5-√3i must be the other root
Step-by-step explanation:
We know that complex roots must come in pairs. The pairs are complex conjugates. (a+bi) and (a-bi)
You are missing a sign between -5 and the square root
So if - 5+ sqrt(3) i is a root, then -5 - sqrt(3) i must be a root
if -5 - sqrt(3)i is a root, then -5 + sqrt(3)i must be a root.
I will assume you missed a + sign
-5+√3i is the given root so -5-√3i must be the other root
Step-by-step explanation:
the area of a rectangle is
length × width.
so, in our case, it is
1/3 × 2/3 = (1×2)/(3×3) = 2/9 yd²
We have the following expression:
S = 6x ^ 2
We must clear x from the equation.
For this, we follow the following steps:
Step 1)
Pass 6 to divide:
S / 6 = x ^ 2
Step 2)
Square root on both sides:
+/- root (S / 6) = x
Step 3)
Multiply numerator and denominator by 6:
x = + / - root (6S / 6 * 6)
Step 4)
Rewrite expression:
x = + / - root (6S / 36)
Step 5)
Take root to denominator:
x = + / - (root (6S)) / 6
Answer:
x = + / - (root (6S)) / 6
