Multiplication of Algebraic Expressions
Covid-19 has led the world to go through a phenomenal transition .
E-learning is the future today.
Stay Home , Stay Safe and keep learning!!!
In Multiplication of Algebraic Expressions, we use the laws of exponents.
There are different types of multiplication.
1) Monomial by monomial
2) Monomial by Binomial
3) Polynomial by monomial
4) Trinomial by monomial
5) Trinomial by trinomial
Steps used in multiplication of monomial by monomial
1) Write the two numbers with multiplication sign (x) between them or put a dot. The dot considered as multiplication.
2) Multiply the numbers.
3) If the bases are same then add the exponents.
2) Find the product of p2
3) Find the product of 3ab and 4a2
= 3ab x 4a2
= (3 x 4) x a x a2
b x b
= 12 a1 +2
= 12 a3
4) Multiply : 8p3
= (8 x 4) x p 3+4
= 32 p7
Monomial by Binomial
5) Multiply : 4abc and 5a2
= 4abc . 5a2
= ( 4 x 5)(abc x a2
= 20 a1+ 2
x b1 + (-3)
x c1 + 6
= 20 a3
= 20 a3
[ Make the exponent of 'b' positive]
