My maths teacher set my some homework which we havent covered yet. I wondered what topic this would be under?
Heres the question:
given that x^2-14x+a=(x+b)^2 for all values of x, find the value of a and the value of b.
Any help appreciated
This exercise has to do with "completing the square". With a quadratic and linear term given, what constant would you have to add in order for that to become a perfect square trinomial. Then, your perfect square trinomial becomes a binomial squared.
