Question

Could someone help me with Rational Equations?

Answer 1

\[\frac{ 1 }{ y-1 } + \frac{ 2 }{ y+1} =0\]

Answer 2

multiply each term by the LCD (y-1)(y+1)
so

y + 1 + 2(y - 1) = 0
the rest is easy

Answer 3

ok thanks

Answer 4

yw

Answer 5

\[\frac{ 2 }{ x-3 } - \frac{ 3 }{ x+3} = \frac{ 12 }{ x ^{2} - 9 } \]

Answer 6

x^2 - 9 = (x + 3)(x - 3) so LCD is (x-3)(x+3)
- proceed as above

Answer 7

\[\frac{ 1 }{ 6-x} + \frac{ 2 }{ x+3 } = \frac{ 5x }{ x ^{2} - 3x-18 }\]

Answer 8

can you factor x^2−3x−18?
