Question

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

Answer 1

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:

$ax^2+bx+c=0,~a\neq 0.$

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.

Answer 2

Answer:

7

Step-by-step explanation:

The standard form of a quadratic equation is

y = ax² + bx + c     where a ≠ 1

c is the number without a variable
