Exercițiul E2 vă rog mult..

Answer 1

a)
f(x)=2x²-4x+5
p=-4/2=-2
q=5/2
x²-2x+5/2=0

b)
f(x)=-3x²-8x+11
p=-8/-3=8/3
q=11/(-3)=-11/3
x²+8/3x-11/3=0

c)
f(x)=-7x²+8
p=0/(-7)=0
q=8/(-7)=-8/7
x²-8/7=0

d)
f(x)=4x²-5x
p=-5/4
q=0/4=0
x²-5/4x=0

e)
f(x)=√3x²-4√2x+√3
p=-4√2/√3=-4√6/3
q=√3/√3=1
x²-4√6/3 x-1=0

f)
f(x)=3/2x²-7/3x+5/6
p=(-7/3)/(3/2)=-14/9
q=(5/6)/(3/2)=5/9
x²-14/9x-5/9=0
