Question

0,5c²-(0,5c-1)(c+2)=1

Answer 1

Відповідь:

0,5c²-(0,5c-1)(c+2)=1

0,5c²-(0,5c²+c-c-2) = ;

0,5c²- 0,5c²+2 = 1;

2 ≠ 1;

c є ∅

Answer 2

Let's solve the equation step by step.

0.5c² - (0.5c - 1)(c + 2) = 1

First, let's expand the expression (0.5c - 1)(c + 2):

0.5c² - (0.5c - 1)(c + 2) = 1 0.5c² - (0.5c)(c + 2) - (1)(c + 2) = 1 0.5c² - 0.5c² - c - c - 2 = 1 -2c - 2 = 1

Next, simplify the equation further:

-2c - 2 = 1 -2c = 1 + 2 -2c = 3

Now, divide both sides of the equation by -2 to solve for c:

(-2c)/-2 = 3/-2 c = -3/2

Therefore, the solution to the equation is c = -3/2.
