Give five examples of expressions containing one variable and five examples of expressions containing two variables.
(i) x – 4 (ii) 5 – y (iii) 2x + 5
(iv) 10x + 4 (v) 11 – z
(b) Five examples containing two variables are:
(i) 7x – 2y (ii) 5x + 2y – 10 (iii) 6x + z – 2
(iv) 15y – z (v) 9x – 10z
Classify the coefficient of each term in the expression
x2y2 – 10x2y + 5xy2 – 20.
Classify the following polynomials as monomials, binomials, trinomials –z + 5, x + y + z, y + z + 100, ab – ac, 17
write two terms which are like
(i) 7xy (ii) 4mn2 (iii) 21.
Construct:
(a) 3 binomials with only x as a variable;
(b) 3 binomials with x and y as variables;
(c) 3 monomials with x and y as variables;
(d) 2 polynomials with 4 or more terms.
