This is an awesome explanation of quadratic equations. I'm going to share to my daughter who is in year 8, to help her through it.
Just thinking it would be interesting to build on this, and show how we can solve for the roots of the polynomial, through factoring or using formula to solve the roots.
Oh year 8 and quadratics. Typically grade ten students in the Toronto area (my area) see quadratics for the first time.
I could make posts on solving for x-intercepts, factoring and using the quadratic formula. If I recall correctly, I might have made posts on them a few years back. Could start from scratch.
great work you did
please do it will help her in understanding of quadratic equations
