- 3 ( 4 a - 5 b ) = - 3 ∙ 4 a - 3 ∙ ( - 5 b ) = - 12 a + 15 b = 15 b - 12 a
a ( b - c ) = a ∙ b - a ∙ c
What -3 x 4a - -3 x 5b mean?
By the way - 3 ( 4 a - 5 b ) and a ( b - c ) they have already been simplified.
Simplify
-3(4a-5b)
A(b-c) = ab - ac
-3 x 4a - -3 x 5b
-12 - -15 = 3
Is this this the distributive property?
Is this correct?
If not, please explain. I am not sure if I fully understand it or not :-)
