Question

Use square root property to solve this equation, explanations are loved :) its: (z+1)^2=17

Answer 1

z = sqrt(17) - 1
z= -sqrt(17) - 1

Answer 2

\[1-\sqrt{17}, 1+\sqrt{17}\] Is this the correct way to type it as an answer?

Answer 3

\[(z+1)^{2} = 17\] You need to get rid of the squared so to do that you take square root on both sides..\[\sqrt{(z+1)^{2}} = \sqrt{17}\] The square root cancels out the squared leaving you with \[z + 1 = \sqrt{17}\] Subtract 1 from both sides leaving you with the final answer as \[z = \sqrt{17} - 1\]

Answer 4

I forgot the plus minus sign

Answer 5

do you write it as a negative then you put a comma then as positive? two answers?

Answer 6

\[z = \pm \sqrt{17} - 1\]

Answer 7

awesome! Thanks everyone :3
