Question

(c-2)²-c(c-6) и найти его числовое значение прт c=-3

Answer 1

(-5) квадрат-(-3)*(-9)=(-5) квадрат+3*-9=52-27=-2

Answer 2

To find the numerical value of the expression (c-2)² - c(c-6) when c = -3, we simply substitute -3 for c in the expression and then evaluate it.

Step 1: Replace c with -3 in the expression: (-3 - 2)² - (-3)(-3 - 6)

Step 2: Simplify the expression: (-5)² - (-3)(-9)

Step 3: Continue simplification: 25 - 27

Step 4: Final answer: -2

So, the numerical value of the expression (c-2)² - c(c-6) when c = -3 is -2.
