Quadratic Regression

[Sydneystats]

Hi, I've been asked to regress a quadratic model for wages in which an intercept (c) and two variables: education and experience are present. My question being that for this to be a quadratic model would i simply input 'wage = c + education^2 + experience^2' or would i have to do two seperate regressions of 'wage = c + education + education^2' and the same for experience? Also, how would these results be interpreted?
