Question

(а-3)²-6(2-а) при а=0,5​

Answer 1

Ответ:

Объяснение:

=$=a^{2}-6a+9-12+6a=a^2-3=0.5^2-3=0.25-3=-2.75$

Answer 2

To find the value of the expression (а-3)²-6(2-а) when а=0.5, we can substitute 0.5 in place of а and simplify the expression using basic arithmetic operations as follows:

(а-3)²-6(2-а) when а=0.5 = (0.5-3)² - 6(2-0.5) (substituting а=0.5) = (-2.5)² - 6(1.5) (simplifying) = 6.25 - 9 (simplifying) = -2.75

Therefore, the value of the expression (а-3)²-6(2-а) when а=0.5 is -2.75.
