Find which of the following equations are quadratic:

$(x−1)_{2}+(x+2)_{2}+3(x+1)=0$

$(x−1)_{2}+(x+2)_{2}+3(x+1)=0$

Solution: $(x−1)_{2}+(x+2)_{2}+3(x+1)=0$

$⇒x_{2}−2x+1+x_{2}+4x+4+3x+3=0$

$⇒2x_{2}+5x+8=0;$

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

Thus, the given equation is a quadratic equation.

$⇒x_{2}−2x+1+x_{2}+4x+4+3x+3=0$

$⇒2x_{2}+5x+8=0;$

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

Thus, the given equation is a quadratic equation.
