Solve the radical equation $square root of 3 x minus 2 end root equals x minus 4$

hint Hint:

Rearrange the equation and then solve for x.

The correct answer is: x = 9

Complete step by step solution:
Here given equation is $square root of 3 x minus 2 end root equals x minus 4$
On squaring both the sides, we have $left parenthesis square root of 3 x minus 2 end root right parenthesis squared equals left parenthesis x minus 4 right parenthesis squared$

Now, this is a quadratic equation with a = 1, b = -11, c = 18
Roots can be found with, $x equals fraction numerator negative b plus-or-minus square root of b squared minus 4 a c end root over denominator 2 a end fraction$
$x equals fraction numerator 11 plus-or-minus square root of 121 minus 4 cross times 1 cross times 18 end root over denominator 2 cross times 1 end fraction$
$x equals fraction numerator 11 plus-or-minus square root of 49 over denominator 2 end fraction$
$not stretchy rightwards double arrow x equals fraction numerator 11 plus-or-minus 7 over denominator 2 end fraction$
$not stretchy rightwards double arrow x equals 9 text or end text 2$
Here, on substitution in given original equation we get the value of x = 9.
