Solving quadratics by factoring review - Khan Academy
Factoring quadratics makes it easier to find their solutions. This article reviews factoring techniques and gives you a chance to try some practice problems.
Factoring quadratics: common factor + grouping - Khan Academy
We're asked to factor 35k squared plus 100k, minus 15. And because we have a non-1 coefficient out here, the best thing to do is probably to factor this by grouping.
Taking common factor from binomial (video) | Khan Academy
Explore the process of factoring polynomials using the greatest common monomial factor. This involves breaking down coefficients and powers of variables to find the largest common factor, and then …
Solving quadratics by factoring (video) | Khan Academy
And when you have something like this, where you have 1 as the leading coefficient, you don't have to do this two-step factoring. Let me just show you an example.
Khan Academy
Sal factors x^2-14x+40 as (x-4)(x-10) and x^2-x-12 as (x+3)(x-4).
Factoring by grouping (article) | Khan Academy
Learn about a factorization method called "grouping." For example, we can use grouping to write 2x²+8x+3x+12 as (2x+3) (x+4).
GCF & LCM word problems (video) | Khan Academy
Here we have a couple of word problems--one searching for the least common multiple and the other for the greatest common factor. Just read them with us slowly and follow along. You'll get it.
Perfect square factorization intro (video) | Khan Academy
Video transcript - [Narrator] We're going to learn to recognize and factor perfect square polynomials in this video. So for example, say I have the polynomial x squared plus six x plus nine. And then …
Factoring using the difference of squares pattern - Khan Academy
Factorization goes the other way: suppose we have an expression that is the difference of two squares, like x²-25 or 49x²-y², then we can factor is using the roots of those squares.
