With the thorough analysis of the CBSE’s examination pattern to be followed in the annual exams, subject experts at jagranjosh has designed this CBSE Class 9 Mathematics Practice Paper which will make you familiar with important questions that will ultimately help you prepare better for the annual exams 2017-2018.
Structure of CBSE Class 9 Mathematics Solved Practice Paper : Set-II:
Solving this practice paper will help you fine tune your prapartion for the final exam letting you know your weak areas which you can recover with more practice and revision.
Some of the sample questions from CBSE Class 9 Mathematics Solved Practice Paper : Set-II are given below:
Q. Find out the common factor in quadratic polynomials x2 + 8x + 15 and x2 + 3x −10.
Here, x2 + 8x + 15 = x2 + 5x + 8x + 15 [Splitting the middle term]
= x(x+5) +3(x+5)
Again, x2 + 3x −10 = x2 −2x + 5x −10
Q. Out of 40 students in a 9 class, 28 students passes in the annual examination. If a student is selected at random, then find the probability that student has failed in the exam.
Total number of students = 40
Number of students who passed the examination = 28
Therefore, Number of students failed = 40 − 28 = 12
P(student fail in examination) = 12/40 = 3/10
Q. Show that (x − 1) is a factor of the polynomial f(x)=2x3 − 3x2 +7x − 6.
Here, f(x)=2x3 − 3x2 +7x − 6.
Put, x − 1= 0 or x = l in f(x)
Weget: f(1) = 2 × 13 −3 × 12 +7 × 1 − 6
= 2 – 3 + 7 − 6=0
Hence, (x − 1) is a factor of the polynomial f(x).
