a maths exam Q i am stuck on

[Elite Bullet]

The anwser is y=-5 or y=0 , either will solve the equation so eitehr is the answer. This is like a grade 10 factoring question guys come on . A quadratic function will always have 2 roots, unless it has a double root or complex roots.

Yes and very easy grade 10 maths I can vouch for that being in grade 10 myself. Well easy for myself anyway.

I hope you did the hole thing in paint. Because well to be honest if you didn't your handwriting lacks alot.

I remember how too do this but its been awhile since ive taken a math class (actually had one last semester but i slept through most of it ). I love doing these kind of questions but i tend to over anaylize anything i see, so they tend to be much for diffecult.

Good job Aliasaid.
