Does anyone know how to factor
juin [17]

Answer:

Factoring is taking the greatest factor of an equation/expression and putting it behind parenthesis.

For example:

2+4: Factor it

2 is the greatest factor of the two

SO

2(1+2)

Ill give you a try it and you can factor it. I might check it later on.

42+ 36

If you are looking for something harder:

Which of the following represents the zeros of f(x)=3x^3-10x^2-81x 28? Answer choices: A.) 7, -4,1/3 B.) 7,-4, -1/3 C.) 7,4,1/3
11Alexandr11 [23.1K]
<span>The right function is f(x)=3x^3-10x^2-81x + 28

You can realize that 7 is a root because it is in all the answers.

So you can divide the polynomial by x - 7. If you do it you can find that the quotient is 3x^2 + 11x - 4

Now you can use the quadratic formula to find the other two roots.

If you do it, you will find they are x = 1/3 and x = -4.

So the answer is option A) 7, -4, 1/3

And the polynomial can be written as (x - 7)(x + 4) (x -1/3)

Please help me-<br> f(x) = x2. What is g(x)?
Whitepunk [10]

Answer:

D. g(x) = 3·x²

Step-by-step explanation:

The given parent function, f(x) = x²

The graph of the function, g(x) is narrower than the graph of the function f(x)

Therefore, the coefficient of the quadratic function is larger than 1

The given point on the parabola, g(x) = (1, 3)

Therefore. when x = 1, g(x) = 3

However, when x = 1, f(x) = 1

Therefore, given that g(x) = a·f(x), we get;

a = g(x)/(f(x)) = 3/1 = 3

g(x) = 3·x²

What is the sign of x/y times 7y^3 when x&lt;0 and y&gt;0? A. Positive B. Negative C. Zero​
11111nata11111 [884]

X <0 means x would be negative.

For x/y, a negative divided by a positive would give a negative answer.

A negative multiplied by a positive would result in a negative.

The answer would be B. Negative

Find the distance between the radical form (3,9) and (0,2)
ss7ja [257]

Hey there!

\large\boxed{\sqrt{58}}

Use the pythagorean theorem:

a² + b² = c²

a will be rise and b will be run.

Distance between 9 and 2 is 7.

Distance between 3 and 0 is 3.

Plug those into the equation.

7² + 3² = c²

Square.

49 + 9 = c²

Add.

58 = c²

Square root both sides.

√58 = c

This is the distance in radical form.

Hope this helps!
