Hope it helped you.

Answer 2

Answer:

x = -2 and -14

Step-by-step explanation:

u can use the quadratic formula

D = b^2 - 4ac

here, a = 1

          b= 16

          c= 28

D = 144

take the square root of 144 = 12

then put it in this formula

x = -b (plus & minus) 12 whole divided by 2a

you will get two values that is

x= -2 and -14
