Question

one of the zero of the quadratic polynomial 3x^2-x-4 is? ​

Answer 1

Step-by-step explanation:

Now,

3x

2

−x−4

=3x

2

−4x+3x−4=0

=x(3x−4)+1(3x−4)=0

=(3x−4)(x+1)=0.

So the zeroes of the polynomial are x=

3

4

and x=−1.

Answer 2

Answer:

1

Step-by-step explanation:

3x

2

−x−4

=3x

2

−4x+3x−4=0

=x(3x−4)+1(3x−4)=0

=(3x−4)(x+1)=0.

So the zeroes of the polynomial are x=

3

4

and x=−1.
