Question

Factorise 12a²b + 15ab².​

Answer 1

Answer:

hlo mate here is the answer

Answer 2

Solution:-

We have

$\sf{12a^2b = 2 × 2 × 3 × a × a × b}$

$\sf{15ab^2 = 3 × 5 × a × b × b}$

★ The two terms have 3, a and b as common factors.

Therefore,

$\sf{12a^2b + 15ab^2}$

$\sf{= (3 × a × b × [(2 × 2 × a) + (5 × b)]}$

$\sf{= 3ab × (4a + 5b)}$

$\sf{3ab (4a + 5b)}$

⠀⠀⠀⠀⠀⠀⠀$\boxed{\sf{\orange{(Required\: factor\: form)}}}$
