Let p(x) = x2 + 2x − 3. (iii) The tens and units place of a two digit number is, Divide first polynomial by second polynomial and write the answer in the form ‘Dividend = Divisor. (i) (vi) Ordinate means y coordinate of point H. So, ordinate of point H is -3. ∴ Number of trees in the village after x years Remainder = 2a3 − a2 − a So, the polynomial 5p is a linear polynomial. (ii) A polynomial having only two terms is called a binomial. NCERT Solutions for Class 9 Maths Exercise 4.3. = Total area of the farm − Area of the square plot (x2 – 6x)2 – 8(x2 – 6x + 8) – 64 =5x2-3y2+7y2+2xy+9x2+4xy=5x2+9x2-3y2+7y2+2xy+4xy=14x2+4y2+6xy The standard form of the polynomial is 3 + 5m + m3 or m3 + 5m + 3. Dividend = Divisor × Quotient + Remainder = 2a4 + 2a2b2 + 3a2b2 + 3b4 − a4 − b4 + 2a2b2 The sum of the powers of the variables in the polynomial m3n7-3m5n+mn are 3 + 7 = 10, 5 + 1 = 6 and 1 + 1 = 2. 2m2+5m-3=2m2+6m-m-3=2mm+3-1m+3=m+32m-1 The degree of the polynomial x2 is 2. (ii) px = 2x2 - 53x + 5 then p53. The degree of the polynomial 2x2 + 3x + 1 is 2. 2 - 5 x=2-5x12 Breadth of the rectangular farm = (a2 + b2) m Hence, the correct answer is option (A). Classify the following polynomials as linear, quadratic and cubic polynomial. = a + bx GO BACK TO CLASS IX MATHS ALL CHAPTERS SOLUTIONS, NCERT Solutions for Class 11 English (Hornbill) Poem – Childhood, NCERT Solutions for Class 11 English (Hornbill) Lesson 5 – The Ailing Planet: the Green Movement’s Role, NCERT Solutions for Class 11 English (Hornbill) Poem – The Voice of the Rain, WBCS 2019 Notification – Apply Online @ pscwbonline.gov.in, NDA & NA UPSC Recruitment National Defense Academy – 2018, UP Police Constable Recruitment 2018 Vacancy 41520 [Apply Online], CTET 2018 Results Online available @ctet.nic.in, WBCS 2019 Results – Prelims, Mains, Interview & Download Merit List, WB Class 12th (Uchha Madhyamik / HS) 2018 State Topper List : Top 10, Important Preparation Tips for CBSE Class 12 Biology Exam, WBSEDCL Admit Card 2018 – Office Executive Interview Call Letter, Airports Authority Of India (AAI) Admit Card, KPCL Junior Engineer Admit Card 2017 Exam Date [Download Now].
