since this equation has irrational roots,,, splitting of terms would be difficult,,but completing the square method will work pretty fine
x^2-60x-2500=0
x^2- 2.30.x +(30)^2 -(30)^2 -2500 =0
(x-30)^2 -900-2500=0
(x-30)^2 = 2500+900
(x-30)^2= 3400
(x-30)= +- 10(√34)
two roots are
x= 30+10√34
x = 30-10√34
