Question

how does this get distributed ?

3(12-7r^2)(10r-5)

Answer 1

\[3(12-7r ^{2})(10r-5)\]
you first have to distribute the three to the first set of ( )

Answer 2

what do you get when you distribute the 3

Answer 3

(3*12)-(3*7r^2) = 36 - 21r^2

Answer 4

i meant 3*-7r^2

Answer 5

yep :) so is that all they are asking or is there anything further that you need to do ?

Answer 6

what next ? i have only done (expressions)(expressions) type of distributions... does the three belong solely to the first (expressions) ?

Answer 7

yes because it is right up against the ( ) it would mean same thing as 3(-4) which is also multiplication! ( )( ) usually means then that you multiply those two together if there is nothing else you can do inside

Answer 8

thanks :)
