Complete the square 4x^2 + 15x + 2 .

Enter your answer in the form a(x + u)^2 + v, where a, u, and v are replaced by numbers.

a(x+u)(x+u) + v

a(x^2 + 2ux + u^2) + v

ax^2 + 2aux + au^2 + v = 4x^2 + 15x + 2

a, u, v are real numbers.

now we know a = 4, then substitute in. 

I think you can take it from here.
