Question

Please Explain This Problem Step By Step. I have Exam.​

Answer 1

Answer:

let alpha as h and beta as k

so according to the question asked,

h and k are the zeroes of the polynomial 2x^2 - 4x + 5

so according to the formula: hk (product of zeroes is c/a)

hk = 5/2

and h+k is  minus of b/a

so h+k is 4/2=2

we have to find h^2 + k^2

by the formula (h + k)^2 = h^2 + k^2 + 2hk

by putting values here,

(2)^2 = h^2 + k^2 + 5/2

4-5/2 = h^2 + k^2

3/2 is h^2 + k^2

by applying certain formulas, we can find the answers of other parts

for part 2) by taking LCM, we will get h+k/hk put values for ans

for part 3)(h-k)^2 = (h+k)^2 - 4hk put values

for part 4) by LCM, ( h^2 + k^2)/( h^2)(k^2)

for last part...it is same as first part...

I hope you get it right...all the best:)
