Answer:
(-1,-2)
Step-by-step explanation:
Let's bring back to memory vertex formula for parabolas.
Where (h,k) is the vertex.
In 
The vertex is (-1,-2)
The is will be -<span>11b3</span><span> - 16b</span>2<span> + </span>4b<span> + </span><span>3</span>
Answer:
12: 7 13: 49
Step-by-step explanation:
35 divided by 5 is 7 so you would get the answer of 6 for 12
7x7 is 49
Maybe D ??
Step by step explanation
Answer:
D
Step-by-step explanation:
Let's substitute a for x²:
x^4 - 3x² - 4
a² - 3a - 4
Now, this looks like something that is much more factorisable:
a² - 3a - 4 = (a - 4)(a + 1)
Plug x² back in for a:
(a - 4)(a + 1)
(x² - 4)(x² + 1)
The first one is a difference of squares, which can be factored into:
x² - 4 = (x + 2)(x - 2)
The second one can also be treated as a difference of squares:
x² + 1 = x² - (-1) = (x + √-1)(x - √-1) = (x + i)(x - i)
The answer is (x + 2)(x - 2)(x + i)(x - i), or D.
