Given : Aditya saw a creeper on the wall of his grandmother's house which was in the shape as shown in the figure.
To Find : How many zeroes does the polynomial (shape of the creeper) have?
Solution:
polynomial (shape of the creeper) cuts the x -axis two times
Hence polynomial (shape of the creeper) have 2 Zeroes
cut x axis at 2 and - 3
Hence zeroes are 2 , - 3
Polynomial = k (x - 2)(x -(-3))
= k (x - 2)(x + 3)
= k(x² + x - 6)
x = 0 y = - 6
=> -6 = k ( 0 + 0 - 6)
=> k = 1
x² + x - 6 is the polynomial
shape represents a Quadratic polynomial
x² + x - 6 is the expansion
