Step-by-step explanation:
Answer: x^2 - 14x + 49
Explanation:
1) Divide the coefficient of x by 2:
14 / 2 = 7
2) so you have to add 7^2 = 49
x^2 - 14x + 49
3) that trinomial is equivalent to:
=> (x - 7)^2
4) prove that using the formula (a - b)^2 = a^2 - 2ab + b^2
(x - 7)^2 = x^2 - 14x + 49
Then you have to add 49 to complete the square. and form a perfect square trinomial.
The answer I believe is the third choice.
3, -2, -7, -12
These all fit into f(n)-5=f(n+1)
if you show the triangle on the graph i can figure it out, or give me the coordinates of the original triangle, can't really do it without those things
