x^2 +12x − 14 = 0
x^2 +12x = 14
x^2 + 12x + 36 = 14 + 36
(x + 6)^2 = 50
At this point, we need to take the square root of both sides.
x + 6 = ±√50
After that is done, we will have: x + 6 = ±5√2
We isolate the variable by subtracting 6 from both sides.
x = -6 ± 5√2
Final answers are: x = -6 + 5√2 , x = -6 - 5√2
Fill in the steps to complete the square:
x^2 +12x − 14 = 0
x^2 +`12x = 14
x^2 + 12x + ? = 14 + ?
We factor and simplify to get: (x+6)^2 = ?
At this point, we need to ?
After that is done, we will have: ? = ?
We get isolate the variable by: ?
Final answers are: ?
