Which polynomial identity will prove that 16 = 25 − 9?
difference of squares
difference of cubes
sum of cubes
square of a binomial

 Difference of Squares

Step-by-step explanation:

Since, According to the polynomial identity of the Difference of Squares,

If a and b are two numbers or polynomials then we can write,

Here our expression,

16 = 25 − 9

Since, we can write,

⇒  ( By applying polynomial identity of  Difference of Squares )

⇒

⇒

Hence proved.

huh? im pretty sure it is in 199

step-by-step explanation:

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
