Question

x²+16x+28=0 solve the equation​

Answer 1

Answer:

-2 and - 14

Step-by-step explanation:

SUM OF EQUATION IS 16

PRODUCT OF EQUATION IS 28

14×2 SO PRODUCT IS 28 AND SUM IS 16.

Answer 2

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
