Question

What is the soution of (Image below)

Answer 1

A

Explanation:

Starting with the original equation:

`√(1-3x) =x+3`

Squaring both sides to remove the root, and expanding the right side:

`1-3x=(x+3)(x+3)`

Multiplying the right side:

`1-3x=x^(2) +6x+9`

Combine like terms:

`x^(2) +9x+8`

Factor:

(x+8)(x+1)

If x+8=0, then x= -8

If x+1=0, then x=-1
