D is a point different from
the ends of segment [AU]
whose length is 18 cm.
ADER and DUQS are two
squares.
AD
Consider AD = x and express the area A(x) of
the polygon SQUARE as a function of x.

Bonjour,
AD = x
AU = 18
donc DU = 18 - x
aire ARED = (AD)²= x²
aire SQUD = (DU)² = (18-x)² =
aire SQUARE = aire SQUD + aire ARED
= (18 - x)² + x²
= 324 - 36x + x² + x²
= 2x² - 36x + 324
