Here, we are asked to differentiate with respect to x. That is what dy/dx stands for. So, we are only concerned with the terms involving x; that is x^3 and 2x. To differentiate you need to time x (and its...

2 + 3 + 7 = 12

6000/12 = 500

7 x 500 = 3500

(3/5) x (3500) = 2100

2100 + 2(500) = 2100 + 1000 = 3100

(3100/6000) x 100 = 52%.

So our first priority is to get all the Xs onto on side and add them together. But we cant do that just yet because of 3(x-2).

so lets move all X values to the left of the equation 3(x-2) + 2x <...

1/(x(1-3x))= A/x+ B/(1-3x) 1= A(1-3x) + B(1-3x)

when x=0    1=A

when x= 1/3     1=B/3 so B=3

1/(x(1-3x))= 1/x + 3/(1-3x)

(m+3)(m+10)

m² + 3m+ 10m + 30

m² +13m+ 30
