Hi there!

[tex] {x}^{2} = 196[/tex]

Take the root (and minus root).
[tex]x = \sqrt{196} \: \: or \: \: x = - \sqrt{196} [/tex]
[tex]x = 14 \: \: \: \: or \: \: x = - 14[/tex]

Answer:

–14, 14

Step-by-step explanation:

x^2 = 196

x = [tex]\sqrt{196}[/tex]

x = [tex]\sqrt{4 * 49}[/tex]

x = [tex]\sqrt{4}[/tex] * [tex]\sqrt{49}[/tex]

x = 2 * 7

x = 14
