Q17 of 90 Page 115

Write 'T' for true and 'F' for false for each of the following:

(i) (5 - 3x2) is a binomial.


(ii) - 8 is a monomial.


(iii) (5a - 9b) - ( - 6a + 2b) = ( - a - 7b).


(iv) When x = 2 and y = 1, the value of is


(v)


(vi) 2x - 5 = 0 x =

(i) True


It has two terms so binomial.


(ii) True


It has single term so monomial.


(iii) False


(5a - 9b) - ( - 6a + 2b) = 5a + 6a - 9b - 2b = 11a - 11b


(iv) True


=


(v) True


Taking the LCM of 4,6 and 2 = 12





(vi) False


2x - 5 = 0
