what is the easy method for primary student to compute this calculation

2007-02-07 21:03:19 · 9 answers · asked by R. s 1 in Mathematics

(Question)1. The function is: g(x)=2x^2-7x+3
Factorised form:

Note: I can't get it right! I was so close I thought but it was +2 instead of +3. The rest of it was correct. Please help me put the function into factorised form.
How do you work it out other than the guess and check method which is time consuming and at times frustrating?

(Question)2. Function: 3x^2-7x-6
Factorised form:

Note: I have tried this one as well. I can't work it out!

I also have a question which asks me to factorise a function completely. Is this different to putting the function in factorised form? Is it just different wording of the same question really?

3. Is there any relationship between the zeros and the coefficient of a function? How are they related?

Please help me out Math whizzes! Thankyou so much.

The solar system consists of the Sun and eight other planets. The moon is a natural satellite of the Earth, but is it also a planet so to speak? If the moon is a planet, then shouldn't the Solar System be consisting of the Sun, the moon and eight other planets?

I'll give you some of the subjects in one chapter and you try to recognize whether it's a college level book or a high school's

this chapter is about genes and stuff :)

lack of dominance: two pages
complementary genes: one page
lethal genes:one page
multiple alleles: 3 pages
rhesus factor: one page
linkage and crodding over: 5 pages
genetic maps: one page

the book is 300 pages and has about 15 chapters.
so what do you think?

How does sedimentary layer dating reconcile itself with ancient objects which have managed to remain unburied (like the clonal colonies of trees in Utah that are at least 80,000 years old).

As I understand it, dating soil by layer is based on the idea that the topsoil is present day, then you go back in time as you dig down, with X feet equal to Y years.

So, might a geologist look at the clonal tree stand and say to a biologist: "Those things are on the surface, therefore they can't be 80,000 years old. If they were, they'd have (whips out a calculator) 59.23 feet of soil above them."

I may be oversimplifying, since I know some fixed lines, like the KT-Boundary exist at a specified position in known strata.

I guess the question I'm asking is: Is soil-layer dating absolute or relative?

To get a date based on depth do you, seemingly paradoxically, have to know the geological history (floods, erosion, past/present river courses) of the area already?

Think about it,they use a machine to send a "signal" into space,it comes back to earth in a zillion peices,collects all together again in this " Box" in your house,and you watch it on your screen....as it happens!..I'm also suspicious of the camera,the phone,and the radio.

i am electrical engineer working in a manufaturing industry which deals with paints, i wanted know if a mechanical engineer give me a calculated B.H.P of a reactor or blender or any equipment which requires a motor for rotating it so how should i convert that B.H.P into electrical H.P so that i can decide which motor to be used for that particular equipment.

.....would a windfarm be capable of capturing all of the potential wind energy or would the majority go to waste, and would the windfarm survive such extreme power mechanically?

I heard on the radio this morning that the London Underground was subject to severe delays, due to the inclement snowy weather.

Just how is it that the snow finds it's way down all those tunnels?!?
