Someone please help me work out these problems, I'm supposed to find the zeros of each function.
f(x)=x^2-7x
f(x)+x^2-9x+20
Also how would I complete the square for this expression?
x^2-15x+?
Please help I'd appreciate it,have to impress my math teacher of a dad.
You'd think that but I've been procrastinating lately, and like my Algebra 200 grades been slipping so he basically gave me a book and a list of questions these were the final three questions and I was trynna get them all right,m at least I thought so but asking my dad isn't a option. But cheating isn't either, thanks for the advice, I'll turn it in as is.
