Q17) What is the sum and the product
Q the polynomial x2 - 4x + 3".
of zelices​

Answer 1

Step-by-step explanation:

Given polynomial: p(x)=x

2

−4x+3

Comparing above equation with standard quadratic polynomial ax

2

+bx+c=0 we get

a=1,b=−4

Let α,β be roots of p(x)

∴α+β=−

a

b

=−

1

(−4)

=4, which is a positive integer.

Hence, option C is correct.

Answer 2

Step-by-step explanation:

X2-4x+3

x2-3x-x+3

x(x-3)-1(x-3)

(x-1) (x-3)

x=1,3

sum= alpha + beeta= -b/ a

1+3=4/1

4=4

hence verified

product= alpha×beeta= c/a

3×1=3/1

3=3

hence verified
