5^2-4*m*(-4m)=0
25+16m^2=0
16m^2= -25
m^2= -25/16
m= +- 5/4
jd persamaan
5/4m^2 -5x +5=0
m^2 -4x +4=0
(m-3)(m+1)=0
akar2nya adlh
m=3 atau m=1
jadi kan didpat m(3)²-5(3)-4m =0
9m-15-4m=0
5m-15=0
5m=15
m=15/5 = 3
maka subtituskan lagi m
jadilah prsmaannya 3x²-5x-12=0
lalu faktorkan, mnjadi (x-3)(3x-4)=0
mka akr yang lain adlah 4/3
