Find which of the following equations are quadratic:

$5x_{2}−8x=−3(7−2x)$

$5x_{2}−8x=−3(7−2x)$

Solution: $5x_{2}−8x=−3(7−2x)$

$⇒5x_{2}−8x=6x−21$

$⇒5x_{2}−14x+21=0;$

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

Thus, the given equation is a quadratic equation.

$⇒5x_{2}−8x=6x−21$

$⇒5x_{2}−14x+21=0;$

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

Thus, the given equation is a quadratic equation.
