Solve each quadratic equation by extracting square roots.
1. ײ=49?
2. ײ-100=0?
3. 2ײ-50=0?
4. ײ-2=79?

Answer: 1. 72. 103. 54. 9Step-by-step explanation: 1.[tex]\sqrt{x^2}[/tex] = [tex]\sqrt{49}[/tex] x=72. [tex]\sqrt{x^2}[/tex] = [tex]\sqrt{100}[/tex]x= 103.[tex]\frac{2x^{2}}{2}[/tex] = [tex]\frac{50}{2}[/tex] [tex]x^{2}[/tex] = 25[tex]\sqrt{x^2}[/tex] = [tex]\sqrt{25}[/tex]x=5 4. [tex]x^{2}[/tex] = 79+2[tex]x^{2}[/tex] = 81[tex]\sqrt{x^2}[/tex] = [tex]\sqrt{81}[/tex]x = 9
