Question

The power P in megawatt(MW), produced between mid-

night and noon by a nuclear power plant is given by

P = 3x² - 42x + 349, where x is the hours of the day.

At what time is the power 250 MW?

(Hint: Take 3x² - 42x + 349 = 250, then find the solution)​

Answer 1

Answer:

by taking 3x2-42x+349=250 we get alpha =3 and beta =11 this means the power is either 3hours or 11hour
