Solve this:
Q If α   a n d   β are the zeroes of the
polynomial 2 x 2 - 7 x + 5 find the value of α 2 + β 2
β           α

Decoder_1 · Accepted Answer

Given poly nomial is 2x2 - 7x + 5
Since
α and β are the zeroes, α + β = - (-7)2 = 72α β = 52 α2+β2β α =(α + β)2 - 2α ββ α=722-2 
5252                    = 494-552= 2925=2910
