Question

factorise: 9a^2b^4+12^3b^3​

Answer 1

GIVEN:

$9 {a}^{2} {b}^{4} + 12 {a}^{3} {b}^{3}$

FACTORIZATION:

$9 {a}^{2} {b}^{4} + 12{a}^{3} {b}^{3} = 3(3 {a}^{2} {b}^{4} + 4 {a}^{3} {b}^{3} ) \\ = 3{a}^{2} ( {b}^{4} + a {b}^{3} ) \\ = 3 {a}^{2} {b}^{3} (b + a)$

Answer 2

hola mate, ur answer is here

GIVEN:

9 {a}^{2} {b}^{4} + 12 {a}^{3} {b}^{3}9a

2

b

4

+12a

3

b

3

FACTORIZATION:

\begin{gathered}9 {a}^{2} {b}^{4} + 12{a}^{3} {b}^{3} = 3(3 {a}^{2} {b}^{4} + 4 {a}^{3} {b}^{3} ) \\ = 3{a}^{2} ( {b}^{4} + a {b}^{3} ) \\ = 3 {a}^{2} {b}^{3} (b + a)\end{gathered}

9a 2 b 4 +12a 3 b 3

=3(3a 2 b 4 +4a 3 b 3 )=3a 2

(b 4 +ab 3 )=3a 2 b 3 (b+a)
