Question 4. Factorize the expression 5ab 2 c 3 – 10a 2 b 3 c – 20a 3 bc 2

Question 4. Factorize the expression 5ab^{2}-10a ^{2} b^{3}c-20a ^{3}bc ^{2}

Factorization methods —

Solution:

To factorize the expression

5ab^{2}-10a ^{2} b^{3}c-20a ^{3}bc ^{2}

we can see that 5ab is common in all three terms here which we take out;

5ab^{2}-10a ^{2} b^{3}c-20a ^{3}bc ^{2}


=5ab(b-2ab^{2}c-4a^{2}c^{2})

 

this is the factorization result for the given expression
