Actually po Activity namin to kanina, ito po answer ko ^_^
3x²-2x=8
3x²-2x-8=0
a=3
b=-2
c=-8
x=-b±√b²-4ac over 2a
x= -(-2)±√(-2)²-4(3)(-8) over 2(3)
x= 2±√4+96 over 6
x= 2±√100 over 6
x= 2±10 over 6
x= 2+10 over 6
x=2
x=2-10 over 6
x=-8 over 6 or -4 over 3
(Sorry po tinatamad ako gumamit nung "paste/edit equation" option... Tyaka po pala yung "over" or "fraction bar" dun sa "Quadratic Formula" simula sa "-b" hanggang sa "√b²-4ac"...Likewise din po pag sinubstitute na... Sana po naintindihan niyo ^_^)
