\[x^2=1044=100\Rightarrow x^2=100\Rightarrow x=\pm\sqrt{100}=\pm10\]

x^2 + 4=104 Subtract 4 from both sides. x^2 = 100 What number times itself is equal to 100? @Kaila_111697

Post what you think it is.

If I had asked what number times itself equals 25, you would have said 5 because 5 times 5 equals 25. Then, I would have said but there is also a negative number that you can multiply times itself and get 25. You would have said 5 because 5 times 5 = 25.

@Kaila_111697 Look at the equation: x^2 + 4=104 We subtracted the 4 from both sides to get x^2 = 100.

But 10 satisfies the equation: x^2 + 4=104 because 10*10 + 4 = 100 +4.
