Hi Robert,
The quadratic formula provides the solutions to ax2+bx+c=0 and is x1,x2=-b±√(b2-4*a*c)/2a
Writing your equation in the standard quadratic form gives:
2m2+2m-10=0 we can factor out and cancel 2, m2+m-5=0, so a=1, b=1, c=-5 putting these values in the
formulas for the solutions gives:
m1=-1/2-(√21/2)
m2=(√21/2)-1/2
