Question

Convert the following to standard form, then write

Answer 1

Answer:

$f(x)=x^2+6x+9$

Step-by-step explanation:

We are required to represent the expression given in the standard form to the quadratic form

Given

$f(x) = (x + 3)^2$

let us square the given expression

f(x)=(x+3)(x+3)

open brackets

$f(x)=x^2+3x+3x+9$

sum the similar terms

$f(x)=x^2+6x+9$
