... this requires considerable algebra, but the use of inverse matrices is very important. Finding the inverse of a 2x2 will give you the idea of what is involved. Finding the inverse requires calculating the determinant. A determinant of a square matrix, denoted by |R|, is a uniquely defined scalar (nu ...

rational expressions and equations
... Multiply numerators and denominators of each fraction. Add numerators. Keep the same denominator the same way we add like fractions. LCD: (x-3)(x+3) – Factored form of x2 – 9. Multiply each fraction by missing part of denominator over itself (only need to do this on right fraction here) to get a com ...
