Answer 2

Answer:

x=1or 2

Step-by-step explanation:

(1/x+4)-1/(x-7)=11/30

(x-7)-(x-4)/(x+4)(x-7)=11/30

-11/x^2-7x+4x-28=11/30

-11/x^2-3x-28=11/30

x^2-3x-28=30/11×-11

x^2-3x-28=-30

x^2-3x-28+30=0

x^2-3x+2=0

a=1 b=-3 c=2

√b^2-4ac=-3^2-4×1×2

=9-8

=√1=1

-b+or- √b^2-4ac/2a

=(3+1)/2 or = (3-1)/2

=4/2 = 2/2

=2 =1
