So the top right answer choice (x - 10)² = 80 has the same solution as x² - 20x + 20 = 0

Step-by-step explanation:

Let's solve your equation step-by-step.

x² − 20x + 20 = 0

For this equation: a = 1, b = -20, c = 20

1x² + −20x + 20 = 0

Step 1: Use quadratic formula with a = 1, b = -20, c = 20.

x = −b ± √b² − 4ac / 2a

x = −(−20) ± √(−20)² − 4(1)(20) / 2(1)

x = 20 ± √320 / 2

x = 10 + 4√5 or x = 10 − 4√5

Let's try the top right answer choice

(x−10)² = 80

Step 1: Simplify both sides of the equation.

x² − 20x + 100 = 80

Step 2: Subtract 80 from both sides.

x² − 20x + 100 − 80 = 80 − 80

x² − 20x + 20 = 0

For this equation: a = 1, b = -20, c = 20

1x² + −20x + 20 = 0

Step 3: Use quadratic formula with a = 1, b = -20, c = 20.

x = −b ± √b² − 4ac / 2a

x = −(−20) ± √(−20)² − 4(1)(20) / 2(1)

x = 20 ± √320 / 2

x = 10 + 4√5 or x = 10 − 4√5
