Solve for x sqrt2x 3 sqrtx 2 1Solutionsqrt2x 3 sqrtx
Solve for x: sqrt(2x - 3) - sqrt(x - 2) = 1
Solution
sqrt(2x - 3) - sqrt(x - 2) = 1
Taking square of both sides:
{sqrt(2x - 3) - sqrt(x - 2) }^2 = 1^2
(2x-3) + (x -2) - 2sqrt(2x-3(x-2) =1
3x -6 - 2sqrt(2x-3(x-2) =0
Now rewriting: (3x-6) = 2sqrt(2x-3(x-2)
Squaring both sides: (3x-6)^2 = 4(2x-3)(x-2)
9x^2 + 36 - 36x = 4( 2x^2 -4x -3x +6)
9x^2 + 36 - 36x = 8x^2 - 28x +24
x^2 -8x +12 =0
Solve by factorisation : x^2 -6x -2x +12 =0
x( x-6) -2(x-6) =0
(x-2)(x-6) =0
x = 2 , 6 ( Solution)
