An irreducible factor of 24x2y2 is(a) x2 (b) y2 (c) x (d) 24x

Answer»

(c) x

An irreducible factor is a factor which cannot be expressed further as a product of factors. Such a factorisation is called an irreducible factorisation.

24x2y2 = 2 × 2 × 2 × 3 × x × x × y × y

Therefore an irreducible factor is x.
