2) The factorisation of 5xy is ______.
3) Factorise : 12x + 36 = ________ .
4) The common factors of 14pq and 28p²q² _________.
5) 5×2×p×p×p×q×r can be written as ________.
6) (x+a) (x+b) = __________.
7) An ___________ is an equality which is true for all the values of the variable.
8) expressions are formed using __________& ___________ .
9) expression contains only one term is known as ___________. 10) 3y(x² + 2 ) = __________​

Answer 1

Answer:

1).1,2,5,7,10,14,35,70

2)

3) 12x+36

=>12(x+3)

4)14pq=14*p*q

= 2*7*p*q

28p^2q^2=28*p^2*q^2

=2*2*7*p*p*q*q

so,14pq=2*7*p*q

28p^2q^2=2*2*7*p*p*q*q

• so,common factor=2*7*p*q
• =14pq
• 5)10p^3qr
• 6)x^2+(a+b)x+ab
• 7)identity
• 8)variables and constant
• 9)monomial
• 10)3y(x^2+2)
• =3yx^2+6y
