How do you simplify the expression # 3a+ab-b #?

Answer 1

Isaiah Anthony

The expression as written cannot be simplified further.

#3a+ab -b# can only be simplified if the values for #a# and #b# are known.

For example, let #a=2# and #b=5#. Substitute the values of #a# and #b# into the expression and simplify.

#(3*2)+(3*5)-5#

#6+15-5#

#16#

To simplify the expression (3a + ab - b), you group like terms together:

(3a + ab - b = (3a) + (ab) + (-b))

Then, you combine the like terms:

(3a + ab - b = 3a + ab - b)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
