Question

(x-13)² помогите срочно​

Answer 1

Ответ:

x²-26x+169

Объяснение:

(a-b)²=a²-2ab+b²

(x-13)²=x²-2·13x+13²=x²-26x+169

(x-13)²=x²-26x+169

Answer 2

$\boxed{ {(a - b)}^{2} = {a}^{2} - 2ab + {b}^{2} }$

${(x - 13)}^{2} = {x}^{2} - 2 \times x \times 13 + {13}^{2} = \boldsymbol{{x}^{2} - 26x + 169}$
