Question

16l²+24lm+9m² solve using identity

Answer 1

Answer:

We know this identity that,

(a+b) ^2=a^+2ab+b^2

so here,

16l^2+24lm+9m^2

=(4l)^2 +2×4l×3m +(3m)^2

=(4l+3m) ^2

Hope it helps!!

Answer 2

Answer:

Step-by-step explanation:

Given that,

16l² + 24lm + 9m²

= ( 4l )² + 2 ( 4l ) ( 3m ) + ( 3m )² (∵( a + b )² = a²+ 2ab + b² )

= ( 4l + 3m )² is the answer.
