can anyone help me plz my problem is 2m squared +2m-12=0 solved using the quadratic formula.
can anyone help me plz my problem is 2m squared +2m-12=0 solved using the quadratic formula
2m^2 + 2m - 12 = 0, solve for m
Solve for m:
2 m^2+2 m-12 = 0
2 m^2+2 m-12 = 2 (m^2+m-6):
2 (m^2+m-6) = 0
Divide both sides by 2:
m^2+m-6 = 0
m = (-1±sqrt(1^2-4 (-6)))/2 = (-1±sqrt(1+24))/2 = (-1±sqrt(25))/2 = (-1±5)/2:
m = (-1+5)/2 or m = (-1-5)/2
(-1+5)/2 = 4/2 = 2:
m = 2 or m = (-1-5)/2
(-1-5)/2 = -6/2 = -3:
Answer: |m = 2 or m = -3
