Question

What is the soution of (Image below)

Answer 1

Answer:

A

Step-by-step explanation:

Starting with the original equation:

$\sqrt{1-3x} =x+3$

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
