Answer: 82
Step-by-step explanation:
Answer:
1. (2x^2+x-1)
Step-by-step explanation:
expanding (2x^2-1)^2. multiplying (x-2) (1-2x)
= 4x^2-4x+1. = x-2x^2-2+4x
= -2x^2+5x-2
(4x^2-4x+1-2x^2+5x-2)
=2x^2+x-1
A=6
B= -1/2
C= 11
I had this one on my test and I got it right have a good day
The correct answer is 317
Y^2-y^1/x^2-x^1
15-10/1-3
slope = -5/2
