| Apr 1, 2019 at 17:33 | comment | added | user5402 | If you have a "simple expression" of a polynomial $P(a,b)$ and you want to make it "more complicated", you can find an invertible function $f$ such that $(a,b)=f(c,d)$ and $(c,d)=f^{-1}(a,b)$. Let $Q=P\circ f$ then the expression you want is $\left(Q\circ f^{-1}\right)(a,b)$. | |
| Mar 31, 2019 at 19:37 | comment | added | Sciolism Apparently | Generating "complex" problems like this is not trivial, especially since the programer would need to offer up a ton of topics (like the Kuta Software people above). They'd also need to make sure that no other site could sneakily reuse the code to produce worksheets on a competing site, using CAPTCHAs and accounts and verification and so on. Here, polynomials, up to degree x, with y terms, using z% fractions, w% decimals, u% of terms using the distributive property over expressions of degree v, with solutions that are s% integer coefficients, t% fractional coefficients, with...gets complex! | |

| Mar 28, 2019 at 18:25 | comment | added | Photon | Thanks for the hint, but as you said, they don't include all the nice properties, I fear, the problems are way too simple (I tried "Simplifying algebraic expressions" and "Multi-step equations")... | |
| Mar 28, 2019 at 18:20 | comment | added | Opal E | If you haven't seen Kuta software, it can generate similar problems to these. However, I'm not sure if they can include all of the properties in one problem. Try Kuta's "Infinite Algebra 2" kutasoftware.com/freeia2.html or "Infinite Precalculus" (accessible from same link). | |
