factorise the expression 2cd - 3de + 4d

now this one i was slightly confused with....as we havent got this in out revision

here is a list of number 2 4 5 6 7 8 from this list,write down a)an odd number b)a multiple of 3 c)a square number d)a factor of 10

factor 4k squared -16k+16

2(x2-10xy)2-1152y4

F(x)= 2xsquared+px+q. Given that f(-3)=0 and f(4)=21. How do I find p and q?

show that x+a is a factor of the polynomial (x+a)4 + (x+c)4 - (a-c)4

factorising help please? 12x + 8y = 4

factorising help please? 12x + 8y = 4 can someone please explain factorisng this in simple and easy steps so i can do all the others.

10xSquared - 17x - 20

how do you factorise

how do you wok out stratified sampling with fractions involved

how to factor

2x62-10x-28=0

How would i go about working out the highest common facteor of 88, 20 and 7??

how do you work out lowest common multiple

what is a prime factor
