Which expression is equivalent to n2 + 26n + 88 for all values of n?
Y_Kistochka [10]

Answer:

(n + 4)(n+ 22)

Step-by-step explanation:

One way to determine which factored expression is accurate is by asking the question: "Which two numbers multiply to 88, but add to 26?" If you are having difficulty using this method, you can always try the guess-and-check method with a multiple choice question. This way involves multiplying the terms inside one set of parentheses with the terms inside the other set of parentheses.

Step #1: Multiply the first terms

(n + 4)(n + 22) ----> n x n = n²

Step #2: Multiply the inside terms

(n + 4)(n + 22) -----> 4 x n = 4n

Step #3: Multiply the outside terms

(n + 4)(n + 22) -----> n x 22 = 22n

Step #4: Multiply the last terms

(n + 4)(n + 22) -----> 4 x 22 = 88

Step #5: Write the new expanded equation and simplify

(n + 4)(n + 22) -----> n² + 4n + 22n + 88 -----> n² + 26n + 88

Prove algebraically what type of function this is (even, odd, or neither).<br>f(x) = x^6 – x^4​
Savatey [412]

Let's see.

We have function f(x)=x^6-x^4. We have to determine if the function is even or odd or neither.

We can find this out in many ways but the assignment specifically asks to prove this algebraically.

Function is even if f(x)=f(-x), so, x^6-x^4=(-x)^6-(-x)^4

Which is true since negative raised to an even power is positive to that same number.

Similarly, function is odd if f(x)=-f(-x), that is,

x^6-x^4\neq-((-x)^6-(-x)^4).

So we have prooved that function f(x) is an even function not an odd function and therefore also not neither.

Hope this helps.
