Need help finding all real or imaginary solutions for these two problems?

Question

49x^2 + 9 = 42x

&

6x = 19x + 25 / x+1 <--(fraction)

Answer 1

49x^2 + 9 = 42x
49x^2-42x+9 =0
(7x-3)^2 = 0
x = 3/7

6x = 19x + 25 /(x+1)
-13x = 25/(x+1)
-13x^2 -13x = 25
13x^2+13x+25 = 0
x =[-13 +/- sqrt(13^2-4(13)(25))]/(2*13)
x = [-13 +/- i*sqrt(1131)]/26
x = -.5 +/- (1/26)i sqrt(1131)
