Question

_ x 2 + 1 = 25 Pls help I need the answer

Answer 1

Answer:

x = ± 2$\sqrt{6}$

Step-by-step explanation:

x² + 1 = 25 ( subtract 1 from both sides )

x² = 24 ( take square root of both sides )

x = ± $\sqrt{24}$ = ± $\sqrt{4(6)}$ = $\sqrt{4}$ × $\sqrt{6}$ = ± 2$\sqrt{6}$

x = - 2$\sqrt{6}$ , x = 2$\sqrt{6}$
