when a = 2 and b= -1 is

-1

Step-by-step explanation:

2−1+  (22−(−1)²) / (1−(2)(−1))

+2(2−(−1)) / (2)(−1)

22−(−1)2 / 1−(2)(−1)

+2(2−(−1)) / (2)(−1)

= -1

f(2x−x2)=−3x2+6x−1

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

i dont know if you cant find a way its best to actually add all of them start from 105 tho
