`alpha` and `beta` are roots of the equation x^2-px+q=0 .Find the equation whose roots are 1 educator answer If `alpha` and `beta` are the roots of 5x^2-px+1=0 and `alpha - beta = 1`, then find p?. If #alpha# and #beta# are the roots of the equation #x^2 - x +1 = 0#, then #alpha^2009 + beta^2009# is?. The beta-2 adrenergic receptor (β 2 adrenoreceptor), also known as ADRB2, is a cell membrane-spanning beta-adrenergic receptor that interacts with epinephrine, a hormone and neurotransmitter (ligand synonym, adrenaline) whose signaling, via adenylate cyclase stimulation through trimeric Gs proteins, increased cAMP, and downstream L-type . The alpha-4 beta-2 nicotinic receptor, also known as the α4β2 receptor, is a type of nicotinic acetylcholine receptor implicated in learning, consisting of α4 and β2 subunits. It is located in the brain , where activation yields post- and presynaptic excitation ,  mainly by increased Na + and K + permeability.. . .
