Question

If 2-3√x =8 , What is the value of x? Please help me in solving this problem, tell me in detail,

Answer 1

The correct answer is option C: 4

Further explanation:

Given equation is a radical equation. In order to solve radical equations, the term with radical is squared to exclude the square root.

Given

$2-3\sqrt{x} =8$

Using subtraction property for equality

$-2+2-3\sqrt{x} =8-2\\-3\sqrt{x} =6$

Dividing both sides by -3

$\frac{-3\sqrt{x} }{-3} = \frac{6}{-3}\\\sqrt{x} =-2$

Taking square on both sides

$(\sqrt{x} )^2 = (-2)^2\\x = 4$

Hence the correct answer is: C. 4
