Best Answer

When you factor a number, you break it down into factors that multiply up to the number. For example, 12=3x4.

There is also prime factorize when you factor the number into primes. For example, 100=2^2x5^2.

To factorise is to find the numbers that divide into the original number by only using prime numbers. For example factorise 20 = 2 times 2 times 5

The answer will depend on where the brackets are. In general the solution would be to expand all the brackets, combine like terms and then factorise.

-5

It is: a(7a-8b)

5a(2b + 1)

Look in an advanced maths book.Improved answer:-If the discriminant of the quadratic expression is less than zero then it's not possible to factor it.

Factorise fully is when brackets are involved in the equation

a²-a = a(a-1)

Type that into the Wolfram Alpha website. It's a maths website that will pretty much do anything to any maths function you require (e.g graph, factorise, integrate etc...) See related links for the website address - alternatively, Google "Wolfram Alpha" and it takes you straight there. Happy maths-ing!

7x2+49x-42 = 7(x2+7x-6)

to put into brackets

you do (245x)
