Find the value of 6+12+16+12+16+⋯. Your answer should be in the form of a+b√c where no factor of c (other than 1) is a square. Find a+b+c
Like so:
I'll leave you to solve the quadratic equation.
That helped a lot! Thanks . But wouldn't a quadratic equation have two solutions?
Yes but would they both be a valid solution to the original? The original expression has to be positive. Will that be true of the soutions to the quadratic?
Ohhh that makes so much more sense! TYSM! :D
