Answer:

A) 3, B) 8 and 4, C) 12

Step-by-step explanation:

There are 3 terms: 8x^2, 4x, and 12.

The coefficiemts are numbers that come before a variable. That's why the coefficients are 8 and 4.

The constant is the number that doesn't come with a variable, thus 12.

Answer:

Part A: 3 terms

Part B: 8 and 4

Part C: 12

Step-by-step explanation:

There are 3 terms, each separated by a + sign.

8 and 4 both have variables attached to them, so they are the coefficients.

12 is the constant because it doesn't have any variables attached to it.

Find the sum: (3x2 + 5x − 8) + (5x2 − 13x − 5)

musickatia [10]

Answer:

$(3x^2+5x-8)+(5x^2-13x-5)=8x^2-8x-13$

Step-by-step explanation:

The given polynomials are,

$3x^2+5x-8,5x^2-13x-5$

In polynomial addition and subtraction only like terms can be added or subtracted.

So,

$=(3x^2+5x-8)+(5x^2-13x-5)$

$=3x^2+5x-8+5x^2-13x-5$

$=3x^2+5x^2+5x-13x-8-5$

$=8x^2-8x-13$

What polynomial has roots of -4, 1, and 6?

Delicious77 [7]

X^3-3x^2-22x+24
the first option is the answer

solution: (x + 4)(x - 1)(x -6) = (x^2 - x + 4x -4)(x - 6)
(x^2 + 3x -4)(x - 6) = x^3 -6x^2 + 3x^2 - 18x - 4x + 24 = x^3 - 3x^2 - 22x + 24

olga nikolaevna [1]

Answer:

See proof below

Step-by-step explanation:

We have to verify that if we substitute $a_n=4^n+2(-1)^n$ in the equation $a_n=3a_{n-1}+4a_{n-2}$ the equality is true.
