  • [tex]5 {x}^{2} = 20[/tex]

  • [tex] {x}^{2} = 20 \div 5[/tex]

  • [tex] {x}^{2} = 4[/tex]

  • [tex]x = \pm2[/tex]

Solution:

[tex]5 {x}^{2} = 20 \\ = > {x}^{2} = \frac{20}{5} \\ = > {x}^{2} = 4 \\ = > x = \sqrt{4} \\ = > x = \sqrt{2 \times 2} \\ = > x = \sqrt{ {2}^{2} } \\ = > x = ±2[/tex]

Answer:

±2
