Dividing Expressions (Junior Cert Mathematics): Flashcards

Simplifying a complicated expression into a simpler one

Direct division and division by factorising first

Numbers in front of variables (e.g., 3 in $3x$)

Letters like $x$ or $y$ representing unknowns

Subtract the powers/exponents

$x^{m-n}$

Divide coefficients, then divide variables (subtract exponents)

Divide each term separately

Factorise numerator and denominator, cancel common factors, simplify

A factor divided by the same factor equals 1

$3x^2$

HCF, grouping, quadratic factorisation, difference of two squares
