If alpha and beta are zeroes of the polynomial x2 - 6x + a.Find the value of a if 3alpha + 2beta = 20 alpha,beta are zeroes of the polynomial x2 - 6x + a.. If alpha and beta are the zeros of the polynomial 2x^2-5x+7, then find the polynomial whose zeros are 2alpha+3beta and 3alpha+2beta.. Best Answer: they are zeros, so set the equation equal to 0 0=x^2+x-2 0=(x+2)(x-1) x=1 and -2 alpha = 1 beta = -2 (it doesnt matter which one actualy equals alpha or beta unless you have instructions about it, choosing either will yeild a correct answer). If #alpha# and #beta# are the zeroes of the quadratic polynomial #x^2 +5x+6# find a quadratic polynomial whose zeroes are #1/ alpha# and #1/ beta?#. If alpha and beta are the zeros of x^2+pc+q, find (Alpha/beta +2)(beta/alpha+2) ?. Alpha and beta are zeroes of quadratic polynomial a^2 -6x+a If alpha and beta are two zeroes of quadratic polynomial 'xsquare-6x+a' then find the value of 'a' in 3alpha+2beta=20. edit Answer.
