Answer:
<h2>(-1, 17)</h2>
Step-by-step explanation:
The vertex form of a quadratic equation:
<em>(h, k)</em> - vertex
<em>use (a + b)² = a² + 2ab + b² </em><em>(*)</em>
<em>h = -1, k = 17</em>

The bolded numbers are the ones that were given in the question. I got the other figures by subtracting as necessary (wherever I could find 2 already filled in figures).
Y= (3/x) - 4. You switch the X and Y and then get the Y by itself
Answer:
Step-by-step explanation:
If you let b = x^2 the problem becomes a whole lot easier. Note that x = √b
x^2 + x - 12
Now factor this trinomial.
(x + 4)(x - 3)
Now put b back into the equation
(√b + 4)(√b - 3)
Answer: the answer is 23434
Step-by-step explanation:first divide 4 by 9 which goes only once, then you would then have 13 which would go only 3 times so 12 minus 13 which is 1 and then goes with 7 to make 17 which means it goes in only 4 times which is 16 meaning the answer is 1 again and then goes with 3 to make 13 and 4 goes in 3 times with 13 to make 12 and then you get 1 which goes into 6 to make 16 and then 4 goes into 16 4 times and then you would get an answer of 23434
