The first three steps of completing the square to solve the quadratic equation x2+8x+5=0 what are next 3 steps

(x+a)^2 - (a)^2 + b

a is half of the second coefficient in front of x (half of 8)

(x+4)^2 -(4)^2 +5

(x+4)^2 -16+5

= (x+4)^2 -9

i’m sorry but i don’t know sorry

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
