Question

solve the equation : x-18/x=6 give your answer correct to two significant figures​

Answer 1

Answer:

(3+3√3) and (3-3√3)

Step-by-step explanation:

we have,

x-18/x = 6

(x²-18)/x = 6

x²-18 = 6x

x²-6x-18 = 0

x = [-(-6)+-√(36+72)]/2(1)

= [6+-√(108)]/2

= [6+-6√3]/2

= [3+-3√3]

so, x = (3+3√3) and (3-3√3) ....ans.
