Sum of zeroes = α + β =√2 Show
Product of zeroes = α β = 1/3 ∴ If α and β are zeroes of any quadratic polynomial, then the quadratic polynomial equation can be written directly as:- x2–(α+β)x +αβ = 0 x2 –(√2)x + (1/3) = 0 3x2-3√2x+1 = 0 Thus, 3x2-3√2x+1 is the quadratic polynomial. Question Open in App Solution Let the zeroes be α and β According to the question:α+β=−3and αβ=2 The quadratic polynomial whose sum and product of the zeroes are given is given by : x²−(α+β)x+αβ ⇒ Then the quadratic polynomial will be : ⇒ x²−(−3)x+2 (adsbygoogle = window.adsbygoogle || []).push({}); ⇒x²+3x+2Hence, the quadratic polynomial is x2+3x+2Suggest Corrections 219 Similar questions Q.
