Question

Help i need this answed as soon as possible

Complete the square and solve. Show all work.

x2 + 4x = 5

Answer 1

take half of 4, then square it to get

(4/2)^2 = 2^2 = 4

so you add 4 to both sides to get this

x^2 + 4x + 4 = 5+4

x^2 + 4x + 4 = 9

Answer 2

the left side is now a perfect square trinomial, which factors to (x+2)^2

so,

x^2 + 4x + 4 = 9

(x+2)^2 = 9

I'll let you finish
