-5x2 + 5x + 60 = 0
Remove the common factor of 5
-x2 + x + 12 = 0
Where the coefficient of x2 is negative, it is best to make it positive by multiplying throughout by -1
x2 - x - 12 = 0
The above equation will factorise.
(x - 4)(x + 3) = 0 ; therefore x - 4 = 0 when x = 4, or x + 3 = 0 when x = -3
The solutions (roots) of this equation are x = 4 and x = -3.
