Following questions of Maharashtra State Board Practice Set 3.5 Class 9 of Chapter 3 Polynomials of Standard 9 have been explained in the video:
Question 8.If (x - 2) is a factor of x³ - mx² + 10x - 20, then find the value of m.
Question 9.By using factor theorem in the following examples, determine whether q(x) is a factor of p(x) or not.i. p(x) = x³ - x² - x -1 ; q(x) = x - 1ii. p(x) = 2x³ - x² - 45 ; q(x) = x - 3
Question 10.If (x³¹ + 31) is divided by (x + 1), then find the remainder.
Question 11.Show that m - 1 is a factor of m²¹ - 1 and m²² - 1.
Question 12.If x - 2 and x - 1/2 both are the factors of the polynomial nx² - 5x + m, then show that
m = n = 2.
Question 13.i. If p(x) = 2 + 5x, then find the value of p(2) + p(- 2) - p(1).
ii. If p(x) = 2x² - 5√3 x + 5, then find the value of p(5√3 ).
