Answer:
<h2>see below</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>given:</h3>
- f(x)=3x³-2x²-12x+8
- -a×-b=ab
- -a×b=-ab
- a²-b²=(a+b)(a-b)
<h3>to do:</h3>
- use factor theorem to show that (x+2) is a factor of f(x)
<h3>tips and formulas:</h3>
- When f(c)=0 then x−c is a factor of f(x)
<h3>let's solve:</h3>
according to the question
x+2=0
x=-2
therefore
we have proven that x+2 is a factor of 3x³-2x²-12x+8
let's factorise 3x³-2x²-12x+8
- factor out x²: x²(3x-2)-12x+8
- factor out -4: x²(3x-2)-4(3x-2)
- group: (x²-4)(3x-2)
- use a²-b² = (a+b)(a-b):
and
we are done
The square with the side length 26 is the Square C. The square with the side length 11 is the Square B. The square with the side length 4.2 is the Square
A. As, 4.2 <11 <26

Answer:
See the attachment. Brainly doesn't like function constructs using f as a function name. Hence the picture.
Answer:
(2,1)
Step-by-step explanation:
The reason is because the vertex is h,k and since the h is 2, the k is one
We get :
2,1.
