a)x^2+2x

we can factorise this by x

x(x+2)

b)2x^2-6x

we can factorise this by 2x

2x(x-3)

c)15x-10x^3

we can factorise this by 5x

5x(3-2x^2)

d)9x^2+3x^3

this can be factorised by 3x^2

3x^2(3+x)

answer:

what is your question that you ask

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
