Classwork Exercise and Series (Mathematics- JSS3): Factorisation

Factorisation of common factors a(b + c) = ab + ac The reverse process, ab + ac = a(b + c), is called taking out the common factor. Consider the factorisation of the expression 5x + 15. Clearly, 5x = 5 X x      15 = 3 X 5 ∴ HCF = 5 Thus 5x + 15 = 5 X x + 3 X 5           = 5(x + [...]
