hey guys, just need to check if my working out and solution is correct.
Find the coefficient of in
My solution
So I started off by separating both brackets into 2 separate equations.
1.
2.
Now I find the coefficient of in equation 1 and I find the coefficient of in equation 2.
So:
now:
1. =
2. =
So now adding both up:
Solution:
Hey Grandad, how do we know how what coefficient to get from 1 and 2.. In this example.. , when you split the two brackets, you have to find the coeff of in the first bracket then find the coeff of in the second bracket.. but in the previous example it was from 1 and from 2.
thanks
EDIT: NEVERMIND, JUST GOT IT
