Learn how to factor a quadratic expression by applying the notions of distributive property, factoring, factoring by grouping, and prime factorization. I apologize for the shaking camera. This is my first video and I notice that when I write underneath my document camera, that this causes the camera and actually my entire desk to shake. I will think about what to do about this because I want future videos to be less shaky so we can focus entirely on the mechanics of how to do the problem. Important Note. I got this problem from Khan Academy. Specifically, this problem was the first problem from exercise "Factoring quadratics with common factor" within the "Quadratics: multiplying and factoring" within the "Algebra 1" course. Therefore, I want to give Khan Academy full credit for providing this video with a problem to be solved. -4x^2 - 28x - 48, factor completely. For those that don't know, Khan Academy is a powerful website where you can learn math from the ground up. I recommend you check it out if you feel like you want to explore your interest in mathematics.
