The correct option is B x2+3x=0
We know that if a quadratic equation ax2+bx+c=0 with roots α,β are transformed the roots α+k and β+k where k is any costant then,
quadratic eqution is a(x−k)2+b(x−k)+c=0
Here, a=1,b=7,c=10,k=2
∴1(x−2)2+7(x−2)+10=0
⇒x2−4x+4+7x−14+10=0
⇒x2+3x+0=0
Hence, the required quadratic equation is x2+3x=0
