Question

check whether the following are quadratic equations x²-2x=(-2)(3-x)​

Answer 1

Answer: yes. It is quadratic equation.

Step-by-step explanation:

LHS = x^2 - 2x

Rhs = (-2)(3-x)

= -6 +2x

Equating both sides

X^2 - 2x = -6 + 2x

=> X^2 -2x -2x + 6 = 0

=> X^2 - 4x + 6 = 0

Answer 2

Step-by-step explanation:

x² - 2x = (-2)(3 - x)

x² - 2x = -6 + 2x

x² - 2x - 2x + 6 = 0

x² - 4x + 6 = 0

yes it is quadratic equation
