Question

1) find the zeroes of the quadratic polynomial 6x2-3-7x and verify the relationship between the zeroes and coffencient of the polynomial ?
[CBSE 2008].

Answer 1

Answer:

6x^2-3-7x

6x^2-7x-3

6x^2-9x+2x-3

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

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

for zeros=p(x) =0

3x+1=0

x= -1/2

2x-3 =0

x=3/2
