First we need to factorise this quadratic. This will be in the form:

0 = (Ax + B)(Cx + D)
You can work this out the values of A, B, C and D by looking at the coefficients in the unfactoris...

6²= 36 8²=6436+64=100√ 100 =10Therefore, 100=∛(125a³)∛(125a³) =∛125 X ∛a³=5 X a =5aSo, 10=5aa=2

In the extract, Scrooge is presented as a miserly, isolated character. Dickens employs a number of methods to demonstrate this to the reader.
Firstly, Dickens' choice of adjectives which describe Sc...

x^2-6x+9(x-3)(x-3)
repeated roots, therefore turning point at x =3, y=0
when x=0, y=9 therefore y intercept = (0,9)

Plants require nitrates to be up-took via active transport for conversion to amino acids which are used to make proteins for growth. To increase yield, farmers need to increase the nitrates available in t...
