What is the value of "c" in the quadratic equation 3x 2 + 5x + 7 = 0? 3 5 7
2 answers:
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:
We know that
the standard quadratic equation is of the following form:
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.
