Answer:

Step-by-step explanation:
Assuming one root of a polynomial function is

Then the other root is

The reason is that , complex roots of polynomial functions occur in pairs.
One complex root is the conjugate of the other.
This means that, if

is a root, then

is also a root.
Y⁴ + 12y² + 36
Now factorize the expression
y⁴ + 6y² + 6y² + 36
= y²(y² + 6) + 6(y² + 6)
= (y² + 6) (y² + 6)
<span>Now 6 is not the perfect square and according to rule, binomial can not be factored as the difference of two perfect squares.
</span>so multiply both.
(y² + 6)² is the answer.
Answer:
the volume is 18 and the surface area is 46
Step-by-step explanation:
Answer:
Step-by-step explanation:
the Pythagorean theorem is
c is the hypotenuse which is the side opposite of the right angle
plug the numbers into the Pythagorean theorem

when squaring a square root, just take the number in the radical and get rid of the radical

subtract 26 from both sides


find the square root of 143
143 is prime so it can just be written as
