Question

(y ³+ 1)²
(2x+1)²
(√3x+1)²

Answer 1

Resolver.

Aplicas
 Productos Notables.

Aplicas.
(a + b)³  = a³ + 3a²b + 3ab² + b³

(y³ + 1)³ =
(y³)³ + 3(y³)² . 1 + 3(y³) . 1² + 1³ =
y⁹ + 3y⁶ + 3y³ + 1


Aplicas.
(a + b)² =
a² + 2ab + b²

(2x + 1)² =
(2x)² + 2(2x)(1) + 1² =
2²x² + 4x + 1 =
4x² + 4x + 1

(√3x + 1)² =
(√3x)² + 2(√3x)(1) + 1² =
3x + 2√3x + 1
