Question

what should be added to 2a square +ab+b square to get 3a square +4ab

Answer 1

Hi there!

.........................................

Let the expression that needs to be added to (2a square+ab+b) be x

$({2a}^{2} + ab + b) + (x) = {3a}^{2} + 4ab$
$x = ( {3a}^{2} + 4ab) - ( {2a}^{2} + ab + b) \\ x = {3a}^{2} + 4ab - {2a }^{2} - ab - b \\ x = {a}^{2} + 3ab - b$
There the expression that has to be added to 2a square + ab +b to get 3a square+4ab is a square +3ab-b.
