Sagot :
[tex] x^{2} + 6x = 16 [/tex]
[tex] x^{2} + 6x - 16 = 0 [/tex]
[tex] (x + 8) (x - 2) = 0 [/tex]
x= -8
x= 2
[tex] x^{2} + 6x - 16 = 0 [/tex]
[tex] (x + 8) (x - 2) = 0 [/tex]
x= -8
x= 2
x²+6x=16
Lets use the completing the square method
x²+6x+9=16+9
(x+3)²=25
x+3=5; x+3=-5
x=2; x=-8
Hope this helps =)
