Question

5- a-1 over a+2=a^2-1 over a+2
5- (a-1/a+2)=a^2-1/a+2

Answer 1

Hmm

Answer 2

Well thhey have the same denominator

Answer 3

I have gotten up to 0=a^2+4a-13, but I believe I went wrong at some point, because it should come out as a whole number..

Answer 4

Ok let me try it out

Answer 5

i got 5 - a - 1/ a^2 -1

Answer 6

WAIT are you simplifying???

Answer 7

I am factoring

Answer 8

5-(a-1)/(a+2) = (a2 -1)/(a+2)
5(a+2)-(a-1)=a2 -1
5a +10 -a +1 =a2 -1
4a +11 =a2 -1
a2 -1 -11 -4a =0
a2 -4a -12 =0
(a-6)(a+2)=0
a_1= -2 and a_2= 6
