Question

find the product of zeroes of quadratic polynimal 3x^2+5x-2....class 10th cbse ​

Answer 1

Answer:

Equating the expression with 0,

3x

2

+5x+2=0

On factorising it further,

3x

2

+3x+2x+2=0

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

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

∴x=

−3

2

or x=−1

∴ The zeroes of 3x

2

+5x+2 are−

3

2

and-1.

Answer 2

Answer:

1/3 and -2

3x^2+5x+2=0

On factorising it further,

3x^2+3x+2x+2=0

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

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

∴x= −3/2

or x=−1
