If it's x²y³ then we know it's the second term of the expansion, that known we can use the combination
C(5, 2) = 5!/(2!.3!) = 10
Then if we had something like
(a + b)^5 our second term would be 10a²b³ but as we can see it's "a²"
And in our case we have 2x as a
So we must do 2² too
2² = 4
10 . 4 = 40
Then our second term of the expansion would be
40x²y³
Equation: L=P*R*T
P=100
R=1.5%=0.015
T=5
Multiply and you get 7.5 as the interest.
X = -2
learn this, it helps
VUX -- vertical line, undefined slope, represented by x = a number
HOY -- horizontal line, 0 slope, represented by y = a number
so x = -2.......is a vertical line which has an undefined slope <=
Here is the answer to your question as This is the way I think it is solved
