Check whether the following is quadratic equations : x² – 2x = (–2) (3 – x)
Share
x2 – 2x = (–2) (3 – x)
simplifying the given equation, we get
x2 – 2x = (–2) (3 – x)
⇒ x² – 2x = – 6 + 2x
⇒ x² – 4x + 6 = 0
or x² – 4x + 6 = 0
This is an equation of type ax² + bx + c = 0.
Hence, the given equation is a quadratic equation.
