Find the solution of the equation: √(x^2-16)-(x-4)=√(x^2-5x+4)
9 months ago

Dear student

sqrt (x- 4) is common in each term hence x = 4 can be. solution. aprt from this

sqrt(x + 4) – sqrt (x- 4) = sqrt (x- 1)

x = 5 is also a solution.

x +4 = x – 4 + x – 1 + 2 sqrt (x^2 – 5x + 4)

x^2 +81 – 18 x = 4 x^2 —20 x + 16

3 x^2 – 2 x – 65 = 0

by solving quadratic equation

x = 5 and -26/6

here – 26/6 is rejected as not satisfied in original equation
