Quadratic Equations

Which of the following equations are not quadratic?

- $x(2x+3)=x+2$
- $(x−2)_{2}+1=2x−3$
- $y(8y+5)=y_{2}+3$
- $y(2y+15)=2(y_{2}+y+8)$

**Correct Answer: ** Option(d)

**Solution: **As we know that in quadratic equation the highest degree of the polynomial is $2$. so all the option have degree of the polynomail $2$ except option D. because in option D the degree of the polynimail is $1$.so the correct option is D
