Find the highest common factor of each component. H.c.f. of 4 and 10 is 2, so:4x² + 10x = 2(2x² + 5x)H.c.f of x² and x is simply x, so:2( 2x² + 5x) = 2x(2x + 5...

Every individual of every species living on the planet has DNA, made up of sections called genes. Mutations to these genes occur over time, resulting in a change to an individual's behaviour or physiology...
