Write in Standard Form f(x)=-(x^2+2x-3)

$f (x) = - (x^{2} + 2 x - 3)$

Step 1

To write a polynomial in standard form, simplify and then arrange the terms in descending order.

$f (x) = a x^{2} + b x + c$

Step 2

Apply the distributive property.

$f (x) = - x^{2} - (2 x) + 3$

Step 3

Simplify.

Multiply $2$ by $- 1$ .

$f (x) = - x^{2} - 2 x + 3$

Multiply $- 1$ by $- 3$ .

$f (x) = - x^{2} - 2 x + 3$
