Question

Find the zeroes of the quadratic polynomials given below. Find the sum and
ofthe zeroes and verify relationship to the coefficients of terms in the polynomial

(1) p(x)=x²-x-6
(ii) p(x)=x²-4x+3
(i) p(x) = x²- 4x +3
(iv) p(x) = x + 2x + 1
In​

Answer 1

Step-by-step explanation:

1.x²-x-6

x²-3x+2x-6=0

x(x-3)+2(x-3)=0

(x-3)(x+2)=0

x=3, x=-2.

a+b=-b/a

3-2=-(-1)/1

1=1

ab=c/a

3(-2)=-6/1

-6=-6

2.x²-4x+3

x²-x-3x+3=0

x(x-1)-3(x-1)=0

(x-1)(x-3)=0

x=1,x=3

a+b=-b/a

1+3=-(-4)/1

4=4

ab=c/a

3(1)=3/1

3. is similar to 2nd

4.x²+2x+1

x²+x+x+1

x(x+1)+(x+1)

(x+1)(x+1)

x=-1, x=-1

a+b=-b/a

-1-1=-(2)/1

-2=-2

ab=c/a

-1(-1)=1/1

1=1.
