ok need help

anonymous · Answer

$$\frac{ x }{ x-4 }=\frac{ x+4 }{ 6 }$$

anonymous · Answer

i know the awnser just dont know how to get there

anonymous · Answer

multiply the denominator of one side by the numerator of the other. then repeat with the other denominator. you should get 6x = (x-4)(x+4). FOIL the right side and set everything equal to zero by subtracting 6x from both sides. then use the quadratic formula

anonymous · Answer

Do cross-multiply. Do you know what it is?

anonymous · Answer

ya but when it comes t foil its where im getting stuck i know the awnser is -2 and 8 but like 6x=$$\left( x \right)\left( x \right)$$ what multipllys to be 16 but adds to be -4

anonymous · Answer

x^2+6x-16 = 0
(x+8)(x-2)
x=2,-8

anonymous · Answer

wait, error in the last one...forgot 6x should be negative

anonymous · Answer

x^2-6x-16 = 0
(x-8)(x+2)
x=-2,8

anonymous · Answer
