Factoring quadratics of the form … `x^2 + bx +c `
MrE uses the BOX METHOD OF FACTORING for lessons 4 and 5. You are welcome to use the techniques in the textbook, but it is too much of a guess and check approach. The BOX METHOD provides a framework that is easier for students to grasp.
The BOX METHOD is linked here, all you need is a computer with sound.
You can also grab it for your iPod on iTunes if you search “MrE Algebra” on the iTunes store!!
