Polynomials Class 10 Exercise 2.1 Solutions – 10th Class Maths 2.1 Exercise Solutions
Question 1.
The graphs of y = p(x) are given below, for some polynomials p(x). Find the number of zeroes of p(x), in each case.
Solution:
i) The number of zeroes is 0′.
As the graph did not intersect the X- axis at any point.
ii) The number of zeroes is 1.
As the graph intersects the X-axis at one point only.
iii) The number of zeroes is 3.
As the graph intersects the X-axis at three points.
iv) The number of zeroes is 2.
As the graph intersects the X-axis at two points.
v) The number of zeroes is 4.
As the graph intersects the X-axis at four points.
vi) The number of zeroes is 3.
As the graph intersects the X-axis at three points.
