Answer:
Step-by-step explanation:
Rewrite this as

Knowing that i-squared = -1:

Both i-squared and 100 are perfect squares, so this simplifies to
±10i
Answer:
Step-by-step explanation:
Hello, as alpha and beta are zeroes of

it means that their sum is alpha+beta=1 and their product alpha*beta=-2.
The polynomial whose zeroes are 2 alpha + 1 and 2 beta + 1, means that the sum of its zeroes is 2(alpha+beta)+2=2+2=4
and the product is (2alpha+1)(2beta+1)=4 alpha*beta + 2(alpha+beta) + 1 = 4 * (-2) + 2*(1) +1 = -8 + 2 + 1 = -5. so one of these polynomials is

Thank you.

<span>The Complete pattern is 85,700, 8,570, 857, 85.7, 8.57, 0.857.It is nothing but just moving the decimal places to the right side.Otherwise each number should multiplied and divided by 10 so that we derived the complete pattern.When you multiply by moving the decimal point to the right, you also need to add a zero to the end of it. This is an alternative method for the pattern.</span>
