Given the quadratic equation:
-6 = x^2 + 4x -1
Determine the value of c.
Explanation:
Quadratic numbers are often expressed in the form:
ax^2 + bx + c, where c is the constant of the function.
Solution:
In order to identify c, we must first simplify the function. This can be done by transposing -6 on the other side of the equation, hence it must be taken note that when transposing a number, the sign changes.
-6 = x^2 + 4x - 1
x^2 + 4x - 1 +6
x^2 + 4x + 5
a = 1
b = 4
c = 5
Final answer:
c = 5
