Find two equivalent expressions for the opposite of the polynomial - x^2+50x-9

- (-x² + 50x - 9); x² - 50x + 9

Step-by-step explanation:

You find the opposite of a polynomial P by changing the sign of every term in P.

P = - x² + 50x - 9

One way to get - P is to put a negative sign in front of the whole expression.

-P = - (-x² + 50x - 9)

Another way is to distribute the - 1 inside the parentheses.

-P = x² - 50x + 9
