-4 sqrt x+2+3= -1

Solve for x???

Question

-4 sqrt x+2+3= -1

Solve for x???

lgbasallote · Answer

$$-4\sqrt{x+2} + 3 = -1$$
subtract 3 ffrom both sides
$$-4\sqrt{x+2} = -1 - 3$$
$$-4 \sqrt{x-2} = -4$$
divide bothsides by -4
$$\sqrt{x-2} = 1$$
square both sides
$$x- 2 = 1$$
add 2 to both sides
$$x = 1 + 2$$
$$x = 3$$
do you get that?

uhh i saw what i did wrong...my typo misled me

lgbasallote · Answer

$$-4\sqrt{x+2} + 3 = -1$$
subtract 3 from both sides
$$-4\sqrt{x+2} = -1 - 3$$
$$-4\sqrt{x+2} = -4$$
divide both sides by -4
$$\sqrt{x+2} = 1$$
square both sides
$$x + 2 = 1$$
subtract 2 from both sides
$$x = 1 - 2$$
$$x = -1$$

now do you get it?

anonymous · Answer

so it is none of the above? because there is no -1 for my options

lgbasallote · Answer

that is of course assuming the question is $$-4 \sqrt{x+2} + 3 = -1$$

lgbasallote · Answer

^is that the question?

anonymous · Answer

yes, that is the question, I worked it out just like you did and was all confused cause there wasn't a -1... agh so it is none of the above

lgbasallote · Answer

yup
