Question

What is the value of "c" in the quadratic equation 3x 2 + 5x + 7 = 0? 3 5 7

Answer 1

7

Explanation:

The standard form of a quadratic equation is

y = ax² + bx + c where a ≠ 1

c is the number without a variable

Answer 2

Answer: The correct option is (C) 7.

Step-by-step explanation: We are given to find the value of 'c' in the following quadratic equation:

`3x^2+5x+7=0~~~~~~~~~~~~~~~~~~~~~~(i)`

We know that

the standard quadratic equation is of the following form:

`ax^2+bx+c=0,~a\\eq 0.`

So, a is the coefficient of x², b is the coefficient of x and c is the constant term in the equation.

Comparing equation (i) with the standard quadratic equation, we get

the constant term, c = 7.

Thus, the required value of c is 7.

Option (C) is CORRECT.
