Question

factorize : 9x²-12xy+4y²​

Answer 1

Step-by-step explanation:

See it is very simple

See it is very simple let's visualise

See it is very simple let's visualise 9x² -12xy +4y²

See it is very simple let's visualise 9x² -12xy +4y² so , (3x)² - 12xy + (2y)²

See it is very simple let's visualise 9x² -12xy +4y² so , (3x)² - 12xy + (2y)² Now , (3x)² - 2(3x)(2y) +(2y)²

See it is very simple let's visualise 9x² -12xy +4y² so , (3x)² - 12xy + (2y)² Now , (3x)² - 2(3x)(2y) +(2y)² (3x-2y)²

See it is very simple let's visualise 9x² -12xy +4y² so , (3x)² - 12xy + (2y)² Now , (3x)² - 2(3x)(2y) +(2y)² (3x-2y)² We Know that : (a-b)² = a² -2ab +b²

See it is very simple let's visualise 9x² -12xy +4y² so , (3x)² - 12xy + (2y)² Now , (3x)² - 2(3x)(2y) +(2y)² (3x-2y)² We Know that : (a-b)² = a² -2ab +b² Answer = (3x-2y)²

Answer 2

the equation :- (a-b)²=a²+b²-2ab

9x²=(3x)² , 4y²=(2y)²

:-3x²+2(3x(3y)-2y²

answer :-(3x-2y)²
