POINTS TO REMEMBER<\/strong><\/p>\n

    \n
  1. Constants and Variables :<\/strong> The numbers which has fixed value is called constant and same at English alphabet which can be assigned any value according to the requirement is called variables.<\/li>\n
  2. Term :<\/strong> A term is a number, (constant), a variable or a combination of numbers and variables.<\/li>\n
  3. Algebraic Expression :<\/strong> An algebraic expression is a collection of one or more terms, which are separated from each other by addition (+) or subtraction (-) signs.<\/li>\n
  4. Types of algebraic expressions :<\/strong>
    \n(i) Monomial : It has only one term
    \n(ii) Binomial : It has two terms
    \n(iii) Trinomial : It has three terms
    \n(iv) Multinomial : It has more than three terms
    \n(v) Polynomial : It has two or more than two terms.
    \nNote<\/strong> : An expression of the type \\(\\frac { 2 }{ 5 }\\) does not form a monomial unless JC is not equal to zero.<\/li>\n
  5. Product:<\/strong> When two or more quantities are multiplied together, the result is called their product.<\/li>\n
  6. Factors :<\/strong> Each of the quantities (numbers or variables) multiplied together to form a term is called a factor of the given term.<\/li>\n
  7. Co-efficient:<\/strong> In a monomial, any factor or group of factors of a term is called the co-efficient of the remaining part of the monomial.<\/li>\n
  8. Degree of a monomial:<\/strong> The degree of a monomial is the exponent of its variable or the sum of the exponents of its variables.<\/li>\n
  9. Degree of a polynomial:<\/strong> The degree of a polynomial is the degree of its highest degree term.<\/li>\n
  10. Like and unlike terms<\/strong> : Terms having the same literal co-efficients or alphabetic letters are called like terms ; whereas the terms with different literal co-efficients are called unlike terms.<\/li>\n
  11. Addition and subtraction<\/strong> : Addition and subtraction of only like terms is possible by adding or subtracting the numerical co-efficients.<\/li>\n
  12. Multiplication and division<\/strong> :
    \n(A) Multiplication :<\/strong>
    \n(i) Multiplications of monomials.
    \n(a) Multiply the numerical co-efficient together
    \n(ii) Multiply the literal co-efficients separately together.
    \n(iii) Combine the like terms.
    \n(B) Division :<\/strong>
    \n(i) Dividing a polynomial by a monomial Divide each term of the polynomial by monomial and simplify each fractions.
    \n(ii) While dividing one polynomial by another polynomial ; arrange the terms of both the dividend and the divisior both in descending or in ascending order of their powers and then divide.<\/li>\n<\/ol>\n

    \n= 7a – 8a = -a<\/p>\n

    Question 35.
    \n\"Selina
    \n<\/strong><\/span><\/p>\n

    Solution:
    \n\"Selina

    Question 36.
    \n<\/strong><\/span>x-(3y- \\(\\overline { 4z-3x }\\) +2z- \\(\\overline { 5y-7x }\\))<\/strong><\/p>\n

    Solution:
    \n<\/strong><\/span>x-(3y- \\(\\overline { 4z-3x }\\) +2z- \\(\\overline { 5y-7x }\\))
    \n= x – (3y – 4z + 3x\u00a0 + 2z -5y + 7x)
    \n= x-(-2y-2z+10x)
    \n= x + 2y + 2z- 10x
    \n= -9x + 2y + 2z<\/p>\n
