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
Answer:
84in
Step-by-step explanation:
10 times 5 = 50 (top half)
7 times 4 = 28 (bottom half)
3 times 4 = 12 / 2= 6 (triagle)
