Question

(x²+2)² va rog am nevoie de ajutor ​

Answer 1

Explicație pas cu pas:

Formulă: (a + b)² = a² + 2ab + b²

(x² + 2)² = (x²)² + 2 • x² • 2 + 2² = x⁴ + 4x² + 4

Answer 2

$\green{ \huge \bf{formula:}}$

$\green{ \bf(a + b) {}^{2} = a {}^{2} + 2ab + {b}^{2} }$

$(x {}^{2} + 2) {}^{2} = (x {}^{2} ) {}^{2} + 2 \times x {}^{2} \times 2 + 2 {}^{2} = \\ = x {}^{4} + 4x {}^{2} + 4$
