Find which of the following equations are quadratic:

$(3x−1)_{2}=5(x+8)$

$(3x−1)_{2}=5(x+8)$

Solution: $(3x−1)_{2}=5(x+8)$

$⇒(9x_{2}−6x+1)=5x+40$

$⇒9x_{2}−11x−39=0;$

which is of the general form $ax_{2}+bx+c=0$

Thus, the given equation is a quadratic equation.

$⇒(9x_{2}−6x+1)=5x+40$

$⇒9x_{2}−11x−39=0;$

which is of the general form $ax_{2}+bx+c=0$

Thus, the given equation is a quadratic equation.
