How do you solve #x^2 – 6x -7 = 0#? Algebra Quadratic Equations and Functions Quadratic Functions and Their Graphs 1 Answer Konstantinos Michailidis Mar 16, 2016 We can write this as follows #x^2-6x-6-1=(x^2-1)-6(x+1)=(x-1)(x+1)-6(x+1)= (x+1)*(x-1-6)=(x+1)*(x-7)# Now from #x^2-6x-7=0=>(x+1)*(x-7)=0# we get that the roots are #x=-1#, #x=7# Answer link Related questions What are the important features of the graphs of quadratic functions?
