Aquadratic equation in standard for written ax^+bc+c=0 where a, b, and c are real numbers and a is not zero. a-true b-false

The correct answer option is A. True.

Step-by-step explanation:

The form is called as the standard form of a quadratic equation where a, b and c are real numbers and a cannot be equal to zero.

'x' is the unknown or what we usually call as the variable in a quadratic equation.

An example of a quadratic equation can be: .

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
