so.. the left-hand-side does indeed simplify to x+7, so the equation does check out.
however, notice something, for the equation of x+7, when x = 6, we get (6) + 7 which is 13.
BUT for the rational, we get
so, even though the siimplification is correct, the rational or original expression is constrained in its domain.
<h2>Answer:</h2>
Option: C is the correct answer.
C.) x = −3.8, 3
<h2>Step-by-step explanation:</h2>The function f(x) is given by:
and the function g(x) is given by:
Now, we are asked to find the solution of the equation:
i.e. we have to find the value of x such that both the functions are equal i.e.
Now, on solving the equation using the quadratic formula i.e. the solution of the equation:
is given by:
Here we have:
Hence, the solution is given by:
