Question

simplify to the lowest terms
16a^2/4a+11b-121b^2/4a+11b

Answer 1

\[\frac{ 16a^2 }{ 4a + 11 } - \frac{ 121b^2 }{ 4a + 11b }\]
i'm guessing you meant that?

Answer 2

yes

Answer 3

find an LCD which in this case is?

Answer 4

i don't know...nothing goes into 121

Answer 5

the LCD is least common denominator, so the left fraction's denominator is the same as the right
4a + 11b is the LCD

Answer 6

ok

Answer 7

so how do I find the lowest term ?

Answer 8

is the answer 105/4a+11b ?

Answer 9

since the right side's denominator is already 4a + 11b we have to multiply the left sides to look like that as well we're missing a B so we multiply the numerator and denominator by
B/B
so it now looks like
\[\frac{ 16a^2b }{ 4a + 11b } - \frac{ 121b^2 }{ 4a + 11b }\]

Answer 10

\[\frac{ 16a^2 - 121b^2 }{ 4a + 11b }\]

Answer 11

ok
