Factorize: -4x squared - 12x

Mathematics
1 answer:
Triss [41]3 years ago
6 0

Answer:

-4x(x +3)

Step-by-step explanation:

Factor out common factors from both terms.

Divide -4 & x from both terms.

(-4x²)/(-4x) = x

(-12x)/(-4x) = 3

x + 3 is the remainder, so keep together.

-4x(x + 3) is your answer

The sum of four consecutive integers is - 18. What is the greatest of these
rjkz [21]

Answer:

-3

The problem:

The sum of four consecutive integers is - 18. What is the greatest of these

integers?

Step-by-step explanation:

If n is the first integer, then n+1 is the second integer, n+2 is the third integer, and n+3 is the fourth integer in consecutive order.

For example if n=8, we are saying n+1=9,n+2=10, and n+3=11, which I think you can see that 8,9,10,11 are consecutive.

So the sum is -18 which means:

n+(n+1)+(n+2)+(n+3)=-18

4n+6=-18

Subtract 6 on both sides:

4n=-18-6

Simplify:

4n=-24

Divide both sides by 4:

n=-6

If n=-6,

then:

n+1=-6+1=-5

n+2=-6+2=-4

n+3=-6+3=-3.

So the 4 consecutive integers whose sum is -18 is: -6,-5,-4, and -3.

The greatest of these integers is -3.
