you need first to try and find the value for both x and y hence initially you set ##y=0## then solve for ##x##. lets try to expand the equation first by opening the bracket.
##y=(x-5)^2##
##Y=X^2-10X+25##
SET ##Y=##0 & SOLVE FOR ##X##.
##0=(X-5)(X-5)##
##X-5=0##
##X=5## ANS. for the x intercept.
SET ##X=0## & SOLVE FOR Y
##Y=(5-5)^2##
##Y=(0-5)^2##
##Y=25##
after setting ##y=0## we have ##x=5## and after setting ##x=0## we have ##y=25## hence ##(025)## and ##(50)##
getting the different values of x and y to plot the equation.
##(025) (116) (29) (34) (41) (50) (61) (74) (89) (916) (1025)##
