Help me find a 3rd degree binomial

Mathematics
1 answer:
Mnenie [13.5K]3 years ago
7 0

Step-by-step explanation:

A binomial expression has two terms. For example, 4x + 5,

The degree of any polynomial refers to the term with the highest exponent on its variable. For example, In expression 4x + 5, the exponent of x is 1 so it is 1st degree polynomial and in the same way, for  since the variable y has the highest exponent i.e., 2 therefore it is 2nd degree polynomial.

Now, third degree binomial with constant term 8 =

As it has two terms where first term is  and second term is 8. Therefore, it is called binomial and since the highest exponent with variable x is 3, therefore it is third degree binomial with constant term of 8.

Answer:

x^{2} -2x-8

Step-by-step explanation:

(f g)(x) is equal to f(x) times g(x).  So you just need to multiply both of the equations together.  Use the foil method to multiply (x+2)(x-4)

(fg)(x)=f(x)*g(x)\\\\(fg)(x)=(x+2)(x-4)\\\\(fg)(x)=x^{2} -4x+2x-8\\\\(fg)(x)=x^{2} -2x-8\\

I have attached an image to better explain the foil method

If y varies directly as x and y=360 when x=180, find y when x=270
kirill115 [55]
Y = kx 360 = k(180) Divide both sides by 180 2 = k So you can now plug in this value into 270 = kx 270 = 2x Now divide both sides by 2 And your answer would be: 135 = x
hope this helps
