How do I solve this problem

(x+1)(x−4)

Step-by-step explanation:

Let's factor x2−3x−4

x2−3x−4

The middle number is -3 and the last number is -4.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -3

Multiply together to get -4

Can you think of the two numbers?

Try 1 and -4:

1+-4 = -3

1*-4 = -4

Fill in the blanks in

(x+_)(x+_)

with 1 and -4 to get...

(x+1)(x-4)

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
