Which of the following is quadratic equation1, 3x²-5x+2=02,3x²_4x+1=3x²=3x+43,4x²-1=44x²+24,0

Answer»

Step-by-step EXPLANATION:

$\longrightarrow\sf 3x^2-5x+2=0$

$\longrightarrow\sf 3x^2-3x-2x+2=0$

$\longrightarrow\sf 3x (x-1)-2 (x-1)=0$

$\longrightarrow\sf (x-1)(3x-1)=0$

$\longrightarrow\sf x-1=0\quad or \quad 3x-1=0$

$\longrightarrow\bf x=1\:or\:x=\dfrac {1}{3}$
