(1) 1 and 2 are the zeros of the polynomial
P (3C) = x2 – 3x + 2
Answers
Step-by-step explanation:
The graphs of y = p(x) are given in the figure given below. for some polynomials p (x). Find the number of zeroes of p (x), in each case
Sol. (i) The given graph is parallel to x-axis. It does not intersect the x-axis.
• It has no zeroes.
(ii) The given graph intersects the x-axis at one point only.
• It has one zero.
(iii) The given graph intersects the x-axis at three points.
• It has three zeroes.
(iv) The given graph intersects the x-axis at two points.
• It has two zeroes.
(v) The given graph intersects the x-axis at four points.
• It has four zeroes.
(vi) The given graph meets the x-axis at three points.
• It has three zeroes.
