Answer:
1936
Step-by-step explanation:
x² + 87 = (x +1)²
x² + 1)² - x² =87
(x² + 2x +1) = 87
2x + 1 = 87 ⇒ x = 44
44² = 1936

Answer:
4x(2x - 1)
Step-by-step explanation:
8x² - 4x ← factor out 4x from each term
= 4x(2x - 1)
Answer:
x - 5 = x - 2 and
x - 5 = 2 - x.
Step-by-step explanation:
x - 5 may be positive or negative so we have:
x - 5 = x - 2
and
x - 5 = - (x - 2)
x - 5 = 2 - x.
