(5 + x)² = ?
​

Answer 1

Answer:

x² + 10x + 25

explanation:

$\hookrightarrow$ (5 + x)²

use the formula: (a+b)² = a² + 2ab + b²

$\hookrightarrow$ x² + 2(5)(x) + (5)²

$\hookrightarrow$ x² + 10x + 25

Answer 2

Solution:

$(5 + x)\² \\\\ \rightarrow (5 + x)(5 + x) \\\\ \rightarrow (5 \times 5) + (5 \times x) + (5 \times x) + (x \times x) \\\\ \rightarrow 25 + 5x + 5x + x^{2} \\\\ \rightarrow \bold{25 + 10x + x^{2} }$
