Answer:
x = -2 or x = -14
Step-by-step explanation:
=> x² + 16x + 28 = 0
16 can be written as " 2+14 "
=> x² + 2x + 14x +28 = 0
Now take x as common from first two terms and take 14 as common from last two terms.
=> x (x + 2) + 14 (x + 2) = 0
Now take (x + 2) as common.
=> (x + 2)(x + 14) = 0
Now x + 2 = 0 or x + 14 = 0
=> x = -2 or x = -14
