Solve the equation using square roots. x² - 15 = 34

Solution:

Given the equation:

x² - 15 = 34

x² = 15 + 34

x² = 49

x =√(7 ×7)

x= √(-7 ×-7)

x = ±7

Another example of such kind of problem can be ;

x² + 45 = 15

x² = 15 - 45

x² = -25

x = ±5i

Solve the equation using square roots. x² - 15 = 34

Summary:

Solving the equation x² - 15 = 34 using square roots we obtain x = ±7
