Simply going to factorise this:
v(v - 1) -2(1 - v):
Note 1 - v = -(v-1)
<span>v(v - 1) -2(1 - v)
</span>
<span>v(v - 1) -2(-(v - 1))
</span>
<span>v(v - 1) +2(v - 1)</span>
(v + 2)(v - 1)
Answer:
uv = 4

Answer:
C. (f – g)(x) = –2x – 2
Step-by-step explanation:
(f – g)(x) = f(x) – g(x)
= (–5x – 4) – (–3x – 2)
= –2x – 2
Apply the Pythagorean Theorem.
a^2 + b^2 = c^2
The largest side is always C.
so 8^2 + 15^2 = 17^2
64 + 225 = 289
The equation true is so it is a right triangle
