  1. Answer:

    (b) x(x + 5) = 2 is the quadratic equation.

    Step-by-step explanation:

    Because;

    A equation having the highest power 2 is called “Quadratic Equation”

    And when we will solve:

    x(x+5)=2

    x^2 + 5x = 2

    And here the equation is having the highest power 2 so it is called the quadratic Equation.

    Hope it helps !!
