Expand it

-(x+3)^2-1
-(x+3)(x+3)-1
-1(x^2+3x+3x+9)-1
-1(x^2+6x+9)-1
-x^2-9x-9-1
-x^2-9x-10

f(x)=-x^2-9x-10

PEMDAS states we do multiplication first.

9 + 5 - 6 + 2

Since it's just addition and subtraction, we calculate left to right

14 - 6 + 2

Solve the inequality. 6x + 3 > 3x + 30 A) x > 9 B) x > 11 C) x > −9 D) x > −11

ANTONII [103]

Subtract 33 from both sides

6x>3x+30-36x>3x+30−3

Simplify 3x+30-33x+30−3 to 3x+273x+27

6x>3x+276x>3x+27

Subtract 3x3x from both sides

6x-3x>276x−3x>27

Simplify 6x-3x6x−3x to 3x3x

3x>273x>27

Divide both sides by 3

3x>\frac{27}{3}x>

3x> 27

Simplify \frac{27}{3}

iren [92.7K]

Answer:

See below

Step-by-step explanation:

Given function

f(x)=x³ + 3x²- 7x - 21

We can find its factors:

x³ + 3x² - 7x - 21 =
x²(x + 3) - 7(x + 3) =
(x² - 7)(x + 3)

We can conclude that the given polynomial function is fully divisible by (x + 3) and the quotient is (x² - 7)

Also one of zeros of the function is -3
