Question

-4r^2(r-2r^2+3rt)

Answer 1

are you simplifying? Or solving for a variable?

Answer 2

simplifying..sorry

Answer 3

okay that's alright. What we want to do first is take care of the inside.

Answer 4

Since there isn't really any like terms we could add or subtract, we could go ahead with distribution of -4r^2

Answer 5

subtracting r - 2r^2?

Answer 6

they aren't like terms. One is squared and the other isn't

Answer 7

if r is r^2 then we could. But r is just well.., r so we can't. Does that make sense?

Answer 8

r has an exponent of 1. r^2 has an exponent of 2

Answer 9

yes

Answer 10

okay. So all we need to do is distribute

Answer 11

-4r^3 + 8r^4 - 12r^2t

Answer 12

?

Answer 13

that's correct.

Answer 14

is that it?

Answer 15

yeup (:
