Step (i) a = 1 [no action necessary in this example]

Step (ii) Rewrite the equation with the constant term on the right side.

x2 + 10x = 4

Step (iii) Complete the square by adding the square of one-half of the coefficient of x to both sides. In this case:

`(10/2)^2=5^2=25`

`x^2+ 10x + 25 = 4 + 25`

`x^2+ 10x + 25 = 29 `

Step (iv) Write the left side as a square:

`(x + 5)^2= 29`

Step (v) Equate and solve

`x+5=+-sqrt(29)`

`x=-5+-sqrt(29)`
