Question

anonymous · Answer

Step #2. (-1) squared would be positive one not negative

anonymous · Answer

so step 2 the answer wrong?
but which one lol the first or second

anonymous · Answer

$$x=1\pm \sqrt{49} \div4$$
$$x=1+\sqrt{49} \div4$$ $$x=2$$
$$x=1-\sqrt{49} \div4$$ $$x=-1.5$$

anonymous · Answer

Lol. The first step #2 is the mistake.

anonymous · Answer

Ahh okay lol thanks

anonymous · Answer

because $$\sqrt{(-1)^{2}}-4(2)(-6) =\sqrt{49} =7$$
