Question

Is the following equation is quadratic equation.

m + 2m + 11 = 0​

Answer 1

Answer:

No.

Step-by-step explanation:

For an equation to be Quadratic, it must satisfy these characteristics:-

• It must be in the form of ax² + bx + c = 0 ( where a, b, c are numbers and a ≠ 0 ).
• Degree (highest power) of the equation must be 2.
• It should have 2 roots (solutions of the equation). Roots can be complex or imaginary and real.

The equation m + 2m + 11 = 0 has only one solution i.e., m = -11/3.

The degree of this equation is 1. ( A linear equation)

Hence, it's not a quadratic equation.

Answer 2

condition for quadratic equation

1 ) must have degree 2

2) follow standard form ax²+bx+c = 0

on comparing this eq with standard form of quadratic equation

we no get the

a =?

it have degree 1

Hence it is not quadratic equation.
