Answer 2

Answer:

g(X)=2x^2-15x+32=0

Step-by-step explanation:

the given equation in the form of ax^2+bx+c

a=2

b= -5

c=7

alpha+beta=-b/a

alpha+beta=-(-5)/2=5/2

(alpha)*(beta)=c/a=7/2

given alpha=alpha+2beta

ß=2alpha+ß

alpha+ß=alpha+2ß+2alpha+ß

alpha+ß=3alpha+3ß=3(alpha+ß)

alpha+ß=3(5/2)=15/2

alpha*ß=2alpha^2+4alpha*ß+alpha*ß+2ß^2

=2(alpha^2+ß^2+2alpha*ß)+alpha*ß

=2(alpha+ß)^2+alpha*ß

=2(5/2)^2+7/2

=25/2+7/2=32/2=16

sub these values in x^2-(alpha+ß)X+alpha*ß=0

x^2-15/2x+16=0

2x^2-15x+32=0
