Question

If α and β are the zeroes of the polynomial 2x^2-4x+5
find the value of Aplha^2-beta^2

Answer 1

Answer:

i am solve this quetion please like me and follow me and mark brainliest

2x² - 4x +5 =0

α+β = -(-4/2) = 2

αβ = 5/2

i)α² +β² = (α+β)² - 2αβ

             = (2)²- 2×(5/2) = 4-5 

             = -1

ii)(α-β)² = (α+β)² - 4αβ

             =(2)² - 4×(5/2) = 4 - 10

             = -6
