Step-by-step explanation:
Complex roots or imaginary roots must come in conjugate pairs. If -4i is a root, that means 4i is also a root.
A possible polynomial is:
y = (x + 4i) (x − 4i)
y = x² − 16i²
y = x² + 16
Answer:
(x² - 8x + 16) = (x-4) (x-4)
Step-by-step explanation:
We have to factorize the given expression
(x²-8x+16)
(x² - 8x + 16 ) = x² - 2(4x) + 4²
= ( x-4)²
[As we know (a-b)² = a² + b² - 2ab]
so (x² - 8x + 16) = (x-4) (x-4) is the factored form of the given expression.
H = 52.2 diameter = 20 cm
<span>radius = 10 cm
Cylinder volume = π <span>• r² • height
</span></span><span>Cylinder volume = PI * 100*52.2

Both 52 and 5x-8 are equal to each other due to being parral.
SO 5x-8=52
Add both sides.
8+8 52+8= 60
5x 60
Now divide both sides by 5 and you get 12=x Hope this helps!
1) -27+1÷ -2 = -26÷ -2 =13
2) 60/-10 = -6
