Question

check whether xsquare-2x=-2(3-x) is a quadratic polynomial​

Answer 1

Answer:

Hello Friend here is your answer...

Step-by-step explanation:

x²-2x= - 2 ( 3-x)

x²-2x= - 2 ( 3-x)x²-2x = -6+x

x²-2x= - 2 ( 3-x)x²-2x = -6+xx²-2x - x = - 6

x²-2x= - 2 ( 3-x)x²-2x = -6+xx²-2x - x = - 6x²-3x = - 6

x²-2x= - 2 ( 3-x)x²-2x = -6+xx²-2x - x = - 6x²-3x = - 6x²-x = - 6/-3

x²-2x= - 2 ( 3-x)x²-2x = -6+xx²-2x - x = - 6x²-3x = - 6x²-x = - 6/-3x²-x = 2

x²-2x= - 2 ( 3-x)x²-2x = -6+xx²-2x - x = - 6x²-3x = - 6x²-x = - 6/-3x²-x = 2 x² - x - 2

So Degree is 2

So Degree is 2 Hence, Quadratic Polynomial.

So Degree is 2 Hence, Quadratic Polynomial. Hence, Verified.

Answer 2

Answer:

Step-by-step explanation:

Given that

x square - 2x = - 2 ( 3 - x )

⇒ x square - 2x = - 6 + 2x ( ∵ - × + = - and - × - = + )

⇒ x square - 2x - 2x + 6 = 0 ( ∵- 6 and 2x are transformed on left side )

⇒ x square - 4x + 6 = 0 ( ∵ - 2x - 2x = - 4x addition )

Hence it is a quadratic polynomial.
