Question

Complete the square for the expression. Write the resulting expression as a binomial squared.
x2 + 3x + _____

Answer 1

x2 + 3x + 6 = (x + 3)2
x2 + 3x + = (x + )2
x2 + 3x + = (x + )2
x2 + 3x + 9= (x + 3)2

Answer 2

\[(x+a)^2=(x+a)(x+a)=x^2+xa+ax+a^2=x^2+2ax+a^2\]

Answer 3

if \(3x = 2ax\) what is \(a\)?
