Question

Please help and thanks !

Answer 1

Answer:

x²+4x+4x+16

x(X+4)+4(X+4)

(x+4)(X+4)=0

x=(-4)

Answer 2

Answer:

x = - 4

Step-by-step explanation:

= − ± 2 − 4 / 2

 

Once in standard form, identify a, b and c from the original equation and plug them into the quadratic formula.

x2+8x+16=0

= 1

= 8

= 1 6

x= − 8 ± 8 ^2 − 4× 1 × 1 6  /  2×   1

= − 8 ± 64 − 4×   1   ×1 6  / 2× 1

= − 8± 6 4 − 6 4 /   2×  1

x = -8 / 2× 1  

x = -8 / 2

x = -4

Hope this answer helps you :)

Have a great day
