factoring ax^2 + bx + c using the AC Method

This factoring basics review shows how to factor quadratic expressions with a number in front and without a number in front. We go step-by-step through the AC method: multiply the first and last terms, find the factor pair that matches the middle term, rewrite the middle term, and then factor by grouping. The lesson also reviews the shortcut when the leading coefficient is 1 and when to factor out a greatest common factor first to make the problem easier. 🔗 Visit www.clopensets.com for full class videos, guided notes, and printable worksheets that go along with this lesson. 🔗 ClopenSets shop: https://www.etsy.com/shop/Clopensets #education #maths #math #highschoolmath #highschool Chapters: 00:00 Introduction and step 1 of the AC method 00:17 Find factor pairs that multiply to AC and add to B 00:47 Step 2: rewrite the middle term 01:21 Step 3: factor by grouping 01:50 Example: factoring 3a^2 - 10a + 7 02:41 Example: factoring with a negative leading combination 03:30 Factor out the GCF first before factoring 04:31 Shortcut when there is no number in front 05:35 Example: factoring with leading coefficient 1 05:55 Example: choosing signs for binomials
