Answer:

#(x-13/2-sqrt141/2)(x-13/2+sqrt141/2)#

Explanation:

#"express in standard form"#

#x^2-13x+7=0#

#"use the "color(blue)"quadratic formula"#

#"with "a=1,b=-13" and "c=7#

#x=(13+-sqrt(169-28))/2#

#color(white)(x)=13/2+-sqrt141/2#

#rArrx^2-13x+7#

#=(x-13/2-sqrt141/2)(x-13/2+sqrt141/2)#
