Answer 1

Answer:

(x+1)^2 = 20

Step-by-step explanation:

x^2 +2x = 19

Take the coefficient of x

2

Divide by 2

2/2=1

Square it

1^2 =1

Add it to each side

x^2 +2x+1 = 19+1

x^2 +2x+1 = 20

(x+1)^2 = 20

Answer 2

Answer:C

Step-by-step explanation:

x^2+2x=19

Add the square of half the coefficient of x to both sides

The coefficient of x is 2

Half of 2=0.5x2=1

Add 1^2 to both sides

x^2+2x+1^2=19+1^2

(x+1)^2=19+1x1

(x+1)^2=19+1

(x+1)^2=20
