Question

Quizplus · Accepted Answer

When solving an equation with one variable, your goal is to isolate the variable on one side of the equal sign. You do this by moving all of the other numbers to the opposite of the equal sign. You move numbers by performing the opposite operation (subtraction/addition and multiplication/division), on both sides of the equation to keep it balanced. (x - 1)² - 5 = 20 The first step is to eliminate the -5 on the left side of the equation. We do this by adding 5 to both sides of the equation. (x - 1)² - 5 + 5 = 20 + 5 (x - 1)² = 25 Now we need to eliminate the exponent on the left side of the equation. We do this by taking the square root of each side. √(x - 1)² = √25 x - 1 = √25 Since the square root of 25 is both 5 and -5, we must solve for both. x - 1 = √25 x - 1 = ±5 11ec0fb7_2744_e1d6_95f0_61ad64db8d25_NR0002_00
