Question

4x-___+4 ВОССТАНОВИ НЕПОЛНЫЙ КВАДРАТ РАЗНОСТИ СРОЧНО!!!

Answer 1

Ответ:

$(2\sqrt{x})^{2}-4\sqrt{x}+2^{2}.$

Пошаговое объяснение:

$a^{2}-ab+b^{2}$ - неполный квадрат разности.

В нашем случае $a=\sqrt{4x}=2\sqrt{x},\ b=\sqrt{4}=2,$ тогда:

$ab=4\sqrt{x}$

$(2\sqrt{x})^{2}-4\sqrt{x}+2^{2}$

Answer 2

To restore the incomplete square in the expression 4x-___+4, we need to find the missing term. The missing term can be found by taking half of the coefficient of 'x' (which is 4) and squaring it. So, half of 4 is 2, and 2 squared is 4.

Therefore, the missing term is 4, and the complete square is:

(2x + 4)^2.

Please note that the original expression you provided, 4x-___+4, does not give us enough information to determine the exact value of the missing term. However, if we assume that the expression should be a perfect square trinomial, the missing term would be 4.
