Question

Factorise it 9x²+4y²+12xy​

Answer 1

Answer:

(3x+2y)² (or (3x+2y)(3x+2y) )

Step-by-step explanation:

(3x)²+(2y)²+(2·3x·4y)

= a²+b²+2ab

∴ (3x+2y)²

Answer 2

Step-by-step explanation:

9x^+4y^+12xy

this means

${(a + b)}^{2} = {a}^{2} + 2ab + {b}^{2}$

it means

ans is

(3x+2y)^

(3x+2y)(3x+2y)
