2(x^2-5x+4) That's the smallest I see. Double check though. I might be misunderstanding the way it ways the answer.

Answer:

2(x-1)(x-4)

Step-by-step explanation:

You can see immediately that 2 is a factor of each term. That lets you write ...

... = 2(x² -5x +4)

To factor further, you need factors of 4 that add to -5. Those would be -1 and -4. Now, you can write ...

... = 2(x -1)(x -4)

_____

<em>Comment on this factorization</em>

It is not uncommon to see quadratics in which the constant is 1 less than the magnitude of the linear term. (4 is 1 less than 5 in this case) Then the constant term and 1 are the constants in the binomial factors. Signs need to be appropriate, of course.

Another way to say this is that when the sum of all the coefficients of the polynomial is zero, 1 is a root and (x -1) is a factor.

Answer:

The next two terms are 55 and 89

Step-by-step explanation:

This is an example of the Fibonacci Sequence: The sum of the previous two numbers equals the next number.

You can see that :

  • 3 + 5 = 8
  • 5 + 8 = 13
  • 8 + 13 = 21
  • 13 + 21 = 24

Rule: the sum of the previous two numbers, equals the next number.

Solve:

  • 3, 5, 8, 13, 21, 34, (21 + 34), (34 + 21 + 34)
  • 3, 5, 8, 13, 21, 34, 55, 89

The next two terms are 55 and 89

What function is graphed below?
lidiya [134]

Answer: y = 2x^4

The graph represents a parabolic-looking shape so it's either a quadratic or some even degree polynomial. This rules out y = -2x^3 and y = 2x^3 as they are cubics with odd degrees

The degree of a polynomial is the largest exponent. It determines the end behavior. In this case, both ends are rising upward together. Because they are rising up in the positive y direction, this means that we cannot have y = -2x^4 as the answer. For example, if x = 2 then y = -2*x^4 = -2*2^4 = -32, but the point (x,y) = (2,-32) isn't on the blue curve. So we can rule y = -2x^4 out.

The fact that y = 2x^4 has a positive leading coefficient tells us that the endpoints point upward.

Which of these graphs represents a function?
mash [69]

Answer:

A, C, and D all do because if you were to hold a pencil up vertically, the line would only intersect it once, if it intersected more, it is not a function

What is the simplified form of x+8/4-x+5/4
kap26 [50]

Answer:

Step-by-step explanation:

x+ 8/4 -x+ 5/4

= x+2+-x +5/4

Combine Like Terms:

x+2+-x+ 5/4

(x+x)+ ( 2 +5/4)

= 13/4
