Ответ:

1.d²-c-25c³=c(d²-25c²)=c(d-5c)(d+5c)

2.4ab-28b+8a-56=4b(a-7)+8(a-7)=(4b+8)(a-7)

3.k³-8k²+16k=k(k²-8k+16)=k(k-4)²

The case for coeds
(1)The results of recent studies of gender differences in education are largely in favour of single-sex school as opposed to coeducational school
Most studies worldwide show that girls at single-sex schools attain the highest achievement; boys at single-sex schools are next; Boys at coed school are next;and girls at coed schools do worst of all.
The results in Britain from 800 public schools, single-sex and coeducational, show that the superior performance of students in single-sex schools is not due to socioeconomic factors but appears instead to be due to single-sex education.
(2) in mill hill, the country high school was divided up into a girl's wing and a boys' wing in 1994. Science that time, the number of pupils scoring high in GCSE exams has risen from 40 percent of 79 percent. Dr Alan Davison, the principal, comments that "men and women's brains are different. So, we need to adapt our teaching to this. It is crucial that we in education recognise that ".
