$Hi \: \: there \\ \\We \: can \: factorise \: this \: polynomial \: and \: that \: will \: be \: its \: equivalent \\ \\ \\Let \: \: me \: do \: it - \\ \\ \\( 2h - 3k ) \: ( h + 5 k ) \: \\ \\ = 2 {h}^{2} + 10hk - 3kh - 15 {k}^{2 } \\ \\ = 2 {h}^{2} + 7kh - 15 {k}^{2 } \:$
Thanks

$(2h - 3k)(h + 5k) \\ = {2h}^{2} + 10hk - 3hk - {15k}^{2} \\ = {2h}^{2} + 7hk - {15k}^{2}$

Hope this helps. - M

i = interest 3% for 30 years

This is a simple dynamical system for whom the the solutions are given as

$S=R[\frac{(i+1)^n-1}{i}](i+1)$

putting values we get

S=2000[\frac{(1.03)^{30}-1}{0.03}](1.03)

To determine the result we use the present value formula of an annuity date

$P = R\frac{1-(1+i)^{-n}}{i}{i+1}$

we need to calculate R so putting the values and solving for R we get

R= $6542.2356
