For the given equation (x+2) (x+4) = x^2 + 6x + 8, how many values of x satisfies this equation?(a) Two values of x(b) One value of x(c) All value of x(d) No value of xI got this question by my college professor while I was bunking the class.Query is from Integration by Partial Fractions in section Integrals of Mathematics – Class 12

Answer»

Right OPTION is (c) All value of x

The EXPLANATION: If we solve the L.H.S. (Left Hand Side) of the EQUATION, we GET the FOLLOWING value.

(x+2) (x+4) = x^2 + 4x + 2x + 8 = x^2 + 6x + 8.

This value is same as the R.H.S. (Right Hand Side).

So, all the values of x satisfy the equality.
