Question

What should be added to 2a²+ab+b² to get 3a²+4ab​

Answer 1

Answer:

• subtract 2a2+ab+b2from 3a2 + 4ab

(2 is square)

Answer 2

Answer:

$a^{2} + 3ab - b^{2}$

Step-by-step explanation:

let the number that should be added be $x$

⇒$2a^{2} + ab + b^{2} + x = 3a^{2} + 4ab$

⇒$x = a^{2} + 3ab - b^{2}$

∴The required number to be added is $a^{2} + 3ab - b^{2}$
