(2-x)²-x(x+1,5)=4 equation
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the equation:
(2-x)^2-x*(x+(3/2)) = 4
Expand expressions:
4 + x^2 - 4*x - x*(x + 3/2) = 4
4 + x^2 - 4*x - x^2 - 3*x/2 = 4
Reducing, you get:
-11*x/2 = 0
Divide both parts of the equation by -11/2
x = 0 / (-11/2)
We get the answer: x = 0
