How do you simplify #6y (5y - 8) + 42y#?

Answer 1

Julia Adams

#30y^2 - 6y#

#6y(5y - 8) + 42y#

First, distribute #6y# to the terms inside the parentheses, #5y# and #-8#. To do this, multiply each term by #6y#.

#6y * 5y = 30y^2# #6y * -8 = -48y#

Re-write the equation to reflect new information:

#30y^2 - 48y + 42y#

Now, combine like terms. #-48y# and #42y# are like terms, so add them together:

#-48y + 42y = -6y#

Therefore, your simplified expression is:

#30y^2 - 6y#

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.
