Hi(adsbygoogle = window.adsbygoogle || []).push({});

Does anyone know any good sites that offer Grade ten math exercises? It's for my sister. Canadian grade ten math, she's doing stuff like quadratic equations, factoring, linear equations.

Also can someone explain to me why when you factor an equation with the quadratic equation the answers signs are reversed from when you do it manually? Like when I do it manually I'll get x= -5, 4 but when I do it with the quadratic equation it becomes x= 5, -4

Thanks! I don't know how to explain it to my sis!
