Its a , i had it yesterday and i got everything right dont worry :))
X^2 * 5,x^4 so B is the answer
It is 0.088 this is just for the 20 characters so dont read this fhehfhryhfrhuehhfuyrhuyhfhefheufrhfyer
So if you wanted the factored form (exg. 1*2*3*4=24)
then this is (5 times 5 times 7)
X = -2 and y = -6. your welcome :)
