4x - 5y = 24
4(6) - 5(0) = 24
24 - 0 = 24
24 = 24 (correct)....so (6,0) is a solution
4(1) - 5(-4) = 24
4 + 20 = 24
24 = 24 (correct)...and (1,-4) is a solution

Answer:
(ab-bc)²
Step-by-step explanation:
- ab(ab-bc)+bc(bc-ab) = ⇒ distribution
- (ab)² - ab*bc + (bc)² - ab*bc = ⇒ regrouping
- (ab)² - 2ab*bc + (bc)² = ⇒ applying (x-y)² = x² -2xy +y² formula
- (ab-bc)² ⇒ final result
