Answer:

D. -3 and  4

Step-by-step explanation:

-12 = -3 x 4

ANSWER

D. -3 and 4

EXPLANATION

The given quadratic trinomial is

{x}^{2}  + x - 12

To factor this we need to find two factors of -12 that sum up to 1, the coefficient of x.

We can see from the table that, when p=-3 and q=4, then p+q =1.

The trinomial can now be factored as:

{x}^{2}  + x - 12 = (x - 3)(x + 4)

The correct answer is D.

Solve equation <br> -8n+7(8+3n)=-16+4n
spin [16.1K]

Answer:

<h2><u><em>-8</em></u></h2>

Step-by-step explanation:

Solve equation

-8n + 7 * (8 + 3n)= -16 + 4n

-8n + 56 + 21n = -16 + 4n

13n + 56 = -16 - 56

13n -4n = -16 - 56

9n = -72

n = -72 : 9

<u><em>n = -8</em></u>
