Practice 8Quick check
How do you factor \(9x^2 - 4\)?
It's \((3x)^2 - 2^2\), a difference of squares.
Practice 9Quick check
Which is a perfect square trinomial?
\(x^2 + 14x + 49 = (x + 7)^2\). The others have the wrong sign or the wrong middle term.
All done?
If you got most of them right, you're ready to move on. If not, reread the lesson and try the ones you missed again in a few days.
