What is the first step when rewriting y=6x^2+18x+14 in the form y=a(x-h)^2+k?
1 answer:
<h3>Answer:</h3>
Factor 6 from the first two terms.
<h3>Step-by-step explanation:</h3>By factoring out "a", you can better see what "h" needs to be.
- y = 6(x^2 +3x) +14 . . . . 6 factored from first 2 terms
- add the square of half the x-coefficient inside parentheses; add the opposite outside: y = 6(x^2 +3x +2.25) +14 -6(2.25)
- rewrite as a square; combine the constants: y = 6(x+1.5)^2 +0.5

Do you have any options? If not, try going with this method to help you understand this problem a little bit better :) Here we go!
-3 + 8(x) - 5 {-8} = ?
8(x) = ? You have to solve this to make it more "easier" if that makes sense
From the looks of it you have to divide by the number, which we call 8
Since, we have only one solution in this problem, the value of "x" is 0
And not all one solution problem(s) always equal "0". .. it can equal any number sometimes
Good Luck!
