<h2>Answer:</h2>

x^2-4x-12\ ------------------\ (x+2)(x-6)\\\\x^2+4x-12\ -----------------\ (x-2)(x+6)\\\\x^2-x-12\ -------------------\ (x-4)(x+3)\\\\x^2-7x-12\ ------------------\ Prime

<h2>Step-by-step explanation:</h2>

1)

x^2-4x-12

This could be factored by using the method of splitting the middle term.

i.e.

x^2-4x-12=x^2-6x+2x-12\\\\i.e.\\\\x^2-4x-12=x(x-6)+2(x-6)\\\\i.e.\\\\x^2-4x-12=(x+2)(x-6)

2)

x^2+4x-12

This could again be factored by the method of splitting the middle term as follows:

x^2+4x-12=x^2+6x-2x-12\\\\i.e.\\\\x^2+4x-12=x(x+6)-2(x+6)\\\\i.e.\\\\x^2+4x-12=(x-2)(x+6)

3)

x^2-x-12

This could be factored by using the method of splitting the middle term.

i.e.

x^2-x-12=x^2-4x+3x-12\\\\i.e.\\\\x^2-x-12=x(x-4)+3(x-4)\\\\i.e.\\\\x^2-x-12=(x-4)(x+3)

4)

x^2-7x-12

This polynomial could not be factored.

Hence, it is a prime expression.

Let f(x)=−3x+2. Write a function g whose graph is a translation 1 unit up from the graph of f.
MariettaO [177]

Answer:

-3x + 3

OR

-3(x-1)

if you want it factored

Step-by-step explanation:

transition up is just adding the desired amount to the equation so

f(x) transitioned up 1 = -3x+3

zimovet [89]

Answer:

add (12/2)^2 to both sides

Step-by-step explanation:

x^2-12x=16

x^2 -12x + (12/2)^2 = 16 + (12/2)^

x- (12/2)^2=52

(x-6)^2=52

Answers:

x= -2 root 3 +6

x= 2 root 3 +6
