1. X² - 15 = 10
First, add 15 to both sides:
X² = 25
Next, take the square root of both sides to solve for x:
X = ±√25
X = ±5
Therefore, the solutions are x = 5 or x = -5.
2. 16x² - 4 = 0
First, add 4 to both sides:
16x² = 4
Next, divide both sides by 16:
x² = 4/16
x² = 1/4
Take the square root of both sides to solve for x:
x = ±√(1/4)
x = ±1/2
Therefore, the solutions are x = 1/2 or x = -1/2.
