Question

Factorise using identity 4x2 +9y2+12xy

Answer 1

Answer:

$4x {}^{2} + 9y {}^{2} + 12xy \\ = (2x) {}^{2} + (3y) { }^{2} +2 (2x)(3y) \\ = (2x + 3y) {}^{2}$

Answer 2

Answer:

4 x^2 + 9 y^2 +12 xy

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

(2x +3y)^2

(2x +3y)^2 =(2x +3y) (2x +3y)

The factors of this equation is

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