Question

What is the solution of square root 1-3x = x+3?

O x = -8 or x = -1
O x=-8
O x=-1
O no solution

Answer 1

Answer: x = -1

Explanation:

To remove the radical on the left side of the equation, square both sides of the equation.

√1−3x2=(x+3)2

Simplify each side of the equation.

1−3x=x2+6x+9

Solve for x

x=−1−8

Exclude the solutions that do not make true

√1−3x=x+3

x=−1
