PLEASE HELP!!!
MEDAL!!
Simplify the expression::
7r^2-49r/r-7

Answer 1

where are the parenthesis to group the numerator and denominator

as typed in you have...

Answer 2

\[7r^2 - 49\frac{ r }{ r } -7\]

Answer 3

I assume you mean

(7r^2 -49r) / (r-7)

Answer 4

\[\frac{ 7r^2-49r }{ r-7 }\]

Answer 5

idk..cause oon my worksheet there is no parenthesis

Answer 6

ok, well if it is just this

7r^2-49r/r-7

then that simplifies to

7r^2 - 49 - 7 = 7r^2 - 56

Answer 7

the one that you wrote was right

Answer 8

But if it is grouped like i did above, it is factoring the numerator, taking out a 7r, and canceling the r - 7 term
\[\frac{ 7r^2-49r }{ r-7 } = \frac{ 7r(r-7) }{ r-7 } = 7r\]
