In algebra, letters are used when numbers are not known. Algebraic terms, such as \(2s\) or \(8y\), leave the multiplication signs out. So rather than \(2 \times s\), write \(2s\), and rather than \(8 ...

Using words like ‘factors,’ ‘denominators’ and ‘multiples’ may be part of a constellation of good math teaching practices ...

Algebraic geometry is a branch of mathematics which, combines abstract algebra, especially commutative algebra, with geometry. It can be seen as the study of solution sets of systems of polynomials.

For ax 2 + bx + c = 0, (α, β) = [–b ± √(b 2 – 4ac)]/2ac, where α and β are the roots of the equation. Sum of roots = –b/a Product of roots = c/a If roots of a quadratic equation are given, then the ...
