How do you multiply #( x + 3)^2#?

Answer 1

#=color(blue)(x^2 + 6x+ 9#

#(x+3)^2#

This statement takes the form of an identity.

#color(blue)((a+b))^2 = a^2 +2ab +b^2#
So, #color(blue)((x+3)^2) = x^2 + 2 . x . 3 + 3^2#
#=color(blue)(x^2 + 6x+ 9#

Answer 2

To multiply ( (x + 3)^2 ), you use the distributive property twice. First, you multiply each term in the first set of parentheses by each term in the second set of parentheses:

( (x + 3) \times (x + 3) = x^2 + 3x + 3x + 9 )

Then, you combine like terms:

( x^2 + 6x + 9 )

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.
