In this video I work through 68 examples of factoring quadratic expressions when a is not equal to one. The first couple of ...

Simplify \(\frac{3t + 6}{3t}\). The numerator of this fraction will factorise as there is a common factor of 3. This gives \(\frac{3(t + 2)}{3t}\). Now, there is clearly a common factor of 3 between ...

The film features a muskox named Lola who struggles with dividing fractions despite being intelligent in other areas of math. Her friend, Arthur the Arctic Fox, teaches her how to approach dividing ...

To check your answer when factorising multiply out the brackets to find if the answer matches with the question. If it doesn't, then you'll know there's something wrong. The first thing to do is find ...

Algebraic factorization and semigroup theory form a cornerstone of contemporary abstract algebra, investigating how elements within algebraic structures decompose into irreducible components, or atoms ...

In her column “Why schools should bring back eighth-grade algebra” (Opinion, March 9), Marcela García seems to argue that, when it comes to teaching children mathematics, one size fits all. Having ...

Many children never master fractions. When asked whether 12/13 + 7/8 was closest to 1, 2, 19, or 21, only 24% of a nationally representative sample of more than 20,000 US 8th graders answered ...
