How many terms are in a^2-ab+8b+b^2-1
DanielleElmas [232]
Remember that the terms of a polynomial are the parts of the polynomial separating by addition and subtraction; in other words, the parts separated by (+) and (-) signs. Knowing this, we can separate the terms of our polynomial:
a^2-ab+8b+b^2-1
- First term: a^2
- Second term: -ab
- Third term: 8b
- Fourth term: b^2
- Fifth term: -1

We can conclude that there are 5 terms in the polynomial a^2-ab+8b+b^2-1.

What are the values of the coefficients and constant term of 0 = 4 – 7x2 + x in standard form?
katen-ka-za [31]

ANSWER

a =  - 7

b = 1

c = 4

EXPLANATION

The given quadratic equation is:

0 = 4 - 7 {x}^{2}  + x

We rewrite in the standard quadratic equation form to obtain,

- 7 {x}^{2}  + x + 4 = 0

Comparing this to the general standard quadratic equation.

a {x}^{2}  + bx + c = 0

We have my

a =  - 7

b = 1

c = 4

Simplify 2(x+3)-4 showing each step
Alex
To simplify this, we first need to distribute the 2 into the parenthesis.

= 2 * x + 2 * 3 - 4

Now, we can simplify:

= 2x + 6 - 4
= 2x + 2

Hope this helps!

Witch statement best describes how to determine whether f(x) =x^3+5x+1 is an even function?
34kurt
A.Determine whether –(x3 + 5x + 1) is equivalent to x3 + 5x + 1. b.Determine whether (–x)3 + 5(–x) + 1 is equivalent to x3 + 5x + 1.
c. Determine whether –x3 + 5x + 1 is equivalent to –(x3 + 5x + 1).
d. Determine whether (–x)3 + 5(–x) + 1 is equivalent to –(x3 + 5x + 1)

A function is even if f(x) = f(-x) for all x.

f(-x) = -x³ + 5(-x) + 1
f(-x) = -x³ - 5x + 1

b.Determine whether (–x)3 + 5(–x) + 1 is equivalent to x3 + 5x + 1.
