x^2-4x+9

=(x^2 - 4x) + 9

=( x^2 - 4x+4) + 9 - 4

=(x - 2)^2 + 5

a = - 2 and b = 5 .. answer//

The values of a and b such that

x^2 - 4x + 9 = (x + a)^2 + bx^2 - 4x + 4 + 5 = (x - 2)^2 + 5

a = -2 and b = 5

a = -2

b = 5

Plug them in.

Expanding (x+a)^2+b gives you ?

In there, whats the coefficient of x?

Answer these & we will proceed.

Hopefully no one will spoil you the answer thereby depriving you from your personal enhancement; that would be very inconsiderate of them. Too late :(
