What is the simplified expression for 3a^2+9ab+5-4a^2-4ab +3?

seraphim [82]

Answer:

$-4a^2+4ab+8$

Step-by-step explanation:

our expression is

$3a^2+9ab+5-4a^2-4ab+3$

we are asked to simplify the expression

in order to that we first bring the like terms together

like terms are those having the same variable or same combination of variables with exactly same degrees

Hence it would be like

$3a^2-4a^2+9ab-4ab+5+3$

now we simplify the like terms

$3a^2-4a^2=-4a^2$

$9ab-4ab=4ab$

$5+3=8$

Hence

$3a^2-4a^2+9ab-4ab+5+3=-4a^2+4ab+8$
