Since p = x² - 7, you can substitute/plug in p for x² - 7
So:
(x² - 7)² - 4x² + 28 = 5
(p)² - 4x² + 28 = 5 You can factor out -4 from (-4x² + 28)
p² - 4(x² - 7) = 5 Plug in p
p² - 4p = 5 Subtract 5
p² - 4p - 5 = 0 Your answer is C
Here, the answer would be: 765 * 11 = 8415 [ About 8 thousands ]
In short, Your Answer would be Option C) <span>The answer should be about 8,000 yards. The student's answer is not correct.
