Question

5x = 2 (4-1) is not a
quadratic polynomial​

Answer 1

Answer:

Comparing the given polynomial with ax

2

+bx+c, we get

a=1,b=5,c=4

p(4)=(4)

2

−5(4)+4

=16+20+4

=0

p(1)=(1)

2

−5(1)+4

=1−5+4

=0

There ,4,1 are the zeroes of polynomial x

2

−5x+4

So, we take α=4 and β=1

Sum of zeroes:

α+β=

a

−b

⇒4+1=(

4

−5

)

⇒5=5

Product of zeroes:

αβ=

a

c

⇒4×1=(

1

4

)

⇒4=4

Hence, proved
