Question

find in the R the solution set
x^2-5x-6=0

Answer 1

(x -6) (x + 1) = 0

x= 6 or -1.

R = { x / x = 6 or x = -1}
R = { x/ x \[\in\] {-1,6} }

Answer 2

thnxxxxxx but hw did u get it ANA2 ?

Answer 3

(x -6) (x + 1) = 0

If a*b = 0
either a or b are zero, or both.

if (x-6) = 0
x = 6

if x + 1 = 0
x = -1.
