A.-x^3+4x+7=2x^2-9

B.x^2+x+2=0

C.3x^3+9x+3x^2=14+x-1

D.5x+4=3x^3-2

Verified Answer :

Answer:

Option B:\(x^{2} +x+2=0\)

Step-by-step explanation:

Any equation of degree 2 is called a quadratic equation.The highest power of the variable is called the degree of the equation.

Quadratic equations can be solved using quadratic formula.

Option B \(x^{2} +x+2=0\) is a quadratic equation as it is degree 2 equation and hence can be solved by using quadratic formula.
