-3x^2-12x-3 How do I factor this function?

Mathematics
1 answer:
Tpy6a [65]3 years ago
6 0

Answer:

Step-by-step explanation:

Take the -3 out:

-3(x^2 +4x+1)

It's best to use the quadratic formula in this case:

(-b±√b²-4ac)/2a

where a =1, b =4, c=1

(-4 ±√16 -4)/2(1)

when you do (-4+√16 -4)/2(1), you will get  -2+√3 = -0.2679..

when you do (-4-√16 -4)/2(1), you will get -2-√3= -3.732..

So, the factored form would look like:

-3(x-2+√3)(x-2-√3)

Hope this helps!

Would really appreciate the brainliest if you think i helped!

the sum of three numbers is 128.The third number is 10 more than the first .The second number 4 times the third number. what are
Ray Of Light [21]
128 = a + + 4(a + 10) + (a + 10)
128 = a + 4a + 40 + a + 10
128 = 6a + 50
128-50 = 6a
78 = 6a
13 = a

1st = a = 13
2nd = 4(a + 10) = 4(23) = 92
3rd = a + 10 = 23

What is the local minimum value of the function? (Round answer to the nearest hundredth) g(x)=x^4-5x^2+4
Serhud [2]
The local minimum of function is an argument x for which the first derivative of function g(x) is equal to zero, so:
g'(x)=0
g'(x)=(x^4-5x^2+4)'=4x^3-10x=0
x(4x^2-10)=0
x=0 or 4x^2-10=0
4x^2-10=0 /4
x^2-10/4=0
x^2-5/2=0
[x-sqrt(5/2)][x+sqrt(5/2)]=0

Now we have to check wchich argument gives the minimum value from x=0, x=sqrt(5/2) and x=-sqrt(5/2).
g(0)=4
g(sqrt(5/2))=25/4-5*5/2+4=4-25/4=-9/4
g(-sqrt(5/2))=-9/4
The answer is sqrt(5/2) and -sqrt(5/2).

(7x10*5)x(3x10*2) in standerd form
marishachu [46]

Answer:

21,000

Step-by-step explanation:

This is more of straightforward multiplication, so I cannot explain much! If you want me to try to do more, then just comment.

(7 * 10 * 5) * (3 * 10 * 2)

= (70 * 5) * (30 * 2)

= (350) * (60)

= 21,000

Thusly, in standard form, the equation given is \boxed{21,000}.

Hope this helps! (:
