Given:

(3x+7)^2 is subtracted from 3.

To find:

The result of the given statement in the standard form of the polynomial.

Solution:

We need to find the result when (3x+7)^2 is subtracted from 3.

So, the resulted polynomial can be written as:

P(x)=3-(3x+7)^2

On simplification, we get

P(x)=3-((3x)^2+2(3x)(7)+(7)^2)               [\because (a+b)^2=a^2+2ab+b^2]

P(x)=3-(9x^2+42x+49)

P(x)=3-9x^2-42x-49

P(x)=-9x^2-42x-46

Therefore, the resulted polynomial in standard form is -9x^2-42x-46.

Answer:

Mistake: -3-5=-2, -3-5=-8

Step-by-step explanation:

-3-(7x+5)+9x=-8+3x+10

-3-7x-5+9x=4x+2

-8+2x=4x+2

-8-2=4x-2x

-10=2x

-10/2=x

The axis of symmetry for the function f(x) = −x2 − 10x + 16 is x = −5. What are the coordinates of the vertex of the graph?
Delicious77 [7]
Just plugin -5 into the equation <span>f(x) = −x^2 − 10x + 16
</span>f(x) = −(-5)^2 − 10(-5) + 16 solve and the answer will be f(x) = 41
<span>
so  (-5, 41) is the answer. </span>

How do you use exponents in a test
katrin2010 [14]

Answer:

An exponent is a number that is to a certain value, like 5^2.

The ^2 means multiply by itself by itself ONCE,

so it would be 5x5.

5^3 means multiply it by itself TWO TIMES,

and going on and on.

Let's say you have a test and the question it's asking is to simplify 5^4.

It's 5x5x5x5, multiplying it by itself FIVE TIMES.

Hope this helped!

olga2289 [7]

Answer:

Step-by-step explanation:

You should factorize so

P2 + 24p + 23

P2 + 23 p + p + 23

P(p + 23) + 1(p + 23)

(p + 23) and ( p + 1) are the factors
