x⁴ - 8x² = 0
x⁴ - 8x² + 16 = 0 + 16
x⁴ - 4x² - 4x² + 16 = 16
x²(x²) - x²(4) - 4(x²) + 4(4) = 16
x²(x² - 4) - 4(x² - 4) = 16
(x² - 4)(x² - 4) = 16
(x² - 4)² = 16
The answer is B.
Answer:

To do this you want to first add 9 1/2 to 62 1/4. 9 1/2 is changed to 9 2/4. 9 2/4 plus 62 1/4 is 71 3/4. Now you have to add 2/14 to 71 3/4 to find how tall their father is. 2/14 plus 71 3/4 is 74. Their dad is 74 inches tall which is equal to 6 feet 2 inches.
