Question
Solve the equation
Solve for x
x=22m3−m2+4m6−4m5+m4+24x=22m3−m2−4m6−4m5+m4+24
Evaluate
x2−(2m−1)xm2−6=0
Multiply the first two terms
x2+x(−2m+1)m2−6=0
Rewrite the expression
x2+(−2m3+m2)x−6=0
Substitute a=1,b=−2m3+m2 and c=−6 into the quadratic formula x=2a−b±b2−4ac
x=22m3−m2±(−2m3+m2)2−4(−6)
