Question

7. Find the zeroes of the quadratic polynomial p(x) = 6x2 -3-7x.
8. Find a quadratic polynomial whose sum and product of its zeroes are and -1 respectively.
9. Find the zeroes of the polynomial x2 - 3 and verify the relationship between the zeroes and
coefficients.​

Answer 1

Answer:

7).6x²-7x-3(rearrange in general form)

6x²+2x-9x-3=0

2x(3x+1)-3(3x+1)=0

(3x+1)(2x-3)=0

3x+1=0. 2x-3=0

x= -1/3. x=3/2

8) Sorry friend please repost this question it is incomplete

9)x²-3

(x-√3)(x+√3)=0

(x-√3)=0. (x+√3)=0

x=√3. x=(-√3)

relationship between the zeroes

Alfa +ß=-b/a

√3+(-√3)=0/1

0=0

Alfa×ß=c/a

√3×(-√3)=-3/1

-3= -3

Hence verified. .

hope it helps you
