To solve the quadratic equation $$\left(x-4\right)^2-25=0$$ , the 1st step results in $$\left(x-4\right)^2=25$$ , the 2nd step results in $$x-4=\pm\sqrt[]{25}$$ , and the 3rd step results in $$x=4\pm5$$ . What was the 3rd step?

add $$4$$ to both sides of the equation and simplify $$\pm\sqrt[]{25}$$

subtract $$4$$ from both sides of the equation and simplify $$\pm\sqrt[]{25}$$

take the square root of $$4$$ and $$25$$

To solve the quadratic equation $$4\left(x+1\right)^2=36$$ , the 1st step results in $$\left(x+1\right)^2=9$$ . The 2nd step results in $$x+1=\pm\sqrt[]{9}$$ . The 3rd step results in $$x=-1\pm3$$ . What was the 3rd step?

subtract $$1$$ from both sides of the equation and simplify $$\sqrt[]{9}$$ .

add $$1$$ to both sides of the equation and simplify $$\sqrt[]{9}$$
