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
I think the answer shouls be 80. But its not given in the options.

Answer:
Step-by-step explanation:
Multiply both sides by –2 (which flips the sign):
Divide both sides by 3:
Subtract 4 from both sides:
Make 4 an improper fraction with a denominator of 3:
