Question

activity on zeroes of a quadratic polynomial

Answer 1

here are you answer!!

OBJECTIVE
1. the shape of the curve when the co-efficient of x value 2 positive.

2. the shape of the curve when the co-efficient of x value 2 is negative.

3. it's no. of zeroes.

method of construction

1. take the cardboard of a convenient size and paste a graph paper on it.

2. consider a quadratic polynomial f(x) = a x value 2 +b x +c.

3. two cases arise.
1. a>0. 2. a<0.

4. find the ordered pairs ( x , fx ) for different value of x

5. plot these ordered pairs in Cartesian plane.

6. join the plotted points by a free hand curve.

hope it's help you!!!
