:

Trying to factor a multi variable polynomial

3.1 Factoring 12a2 - 5ab - 2b2

Try to factor this multi-variable trinomial using trial and error

Found a factorization : (3a - 2b)•(4a + b)

Final result :

(3a - 2b) • (4a + b)

Answer 2

On factorizing 12a²b+15ab² we will get 3ab (4a+5b)

Given:

12a²b+15ab²

[given expression might be wrong the corrected one is (12a²b+15ab²)

To find:

Factorize 12a²b+15ab²

Solution:

Given expression 12a²b+15ab²  

As we know

12 = 3 × 4 and 15 = 3 × 5

a² = a × a  and b² = b × b  

From above data the given expression can written as given below

⇒ (3×4×a×a×b + 3×5×b×b×a )  

Now take out the common terms

⇒ 3×a×b (4×a+5×b)

⇒ 3ab (4a+5b)

Therefore,

On factorizing 12a²b+15ab² we will get 3ab (4a+5b)
