Question
Solve the equation
m1=−248,m2=0,m3=248
Alternative Form
m1≈−0.840896,m2=0,m3≈0.840896
Evaluate
2m5=m×1
Any expression multiplied by 1 remains the same
2m5=m
Add or subtract both sides
2m5−m=0
Factor the expression
m(2m4−1)=0
Separate the equation into 2 possible cases
m=02m4−1=0
Solve the equation
More Steps

Evaluate
2m4−1=0
Move the constant to the right-hand side and change its sign
2m4=0+1
Removing 0 doesn't change the value,so remove it from the expression
2m4=1
Divide both sides
22m4=21
Divide the numbers
m4=21
Take the root of both sides of the equation and remember to use both positive and negative roots
m=±421
