1.	What is the frequency of a photon with a wavelength of 781 nm. Report your answers to three significant digits.The frequency is = _________ s-1
Answer» <P>Explanation: x² + 7x + 10 is the required POLYNOMIAL. Explanation : According to the Question It is given that α and β are the zeroes of a polynomial . SUM of ZEROS (α+β) = -7 Product of Zeros (αβ) = 10 we need to calculate the polynomial. As we know that if the sum of zeros and product of zeros are given we can easily calculate the polynomial . Let the Polynomial be P(x) • P(x) = x²-(sum of zeros)x + (product of zeros) Substitute the value we get ➻ P(x) = x²-(-7)x + (10) ➻ P(x) = x²+7x+10 So, the required polynomial is x² + 7x + 10.

<P>Explanation:

x² + 7x + 10 is the required POLYNOMIAL.

Explanation :

According to the Question

It is given that α and β are the zeroes of a polynomial .

SUM of ZEROS (α+β) = -7

Product of Zeros (αβ) = 10

we need to calculate the polynomial.

As we know that if the sum of zeros and product of zeros are given we can easily calculate the polynomial .

Let the Polynomial be P(x)

• P(x) = x²-(sum of zeros)x + (product of zeros)

Substitute the value we get

➻ P(x) = x²-(-7)x + (10)

➻ P(x) = x²+7x+10

So, the required polynomial is x² + 7x + 10.
