2x²-14x -120=0
x²-7x-60=0
x²-12x+5x -60=0
x(x-12) +5(x-12)=0
(x+5)(x-12)=0
x=-5,x=12
x²-7x-60=0
x²-12x+5x -60=0
x(x-12) +5(x-12)=0
(x+5)(x-12)=0
x=-5,x=12

2xsq.-14x-120=0. (by dividing 2)
=xsq.-7x-60=0
=xsq.-12x+5x-60=0
=x(x-12)+5(x-12)=0
(x-12)(x+5)=0
x-12=0. or. x+5=0
x=12. or. x=-5
So the value of x is -12 or 5.
