What value of g makes the equation true? (x+7)(x-4)=x^2+gx-28

The value of g should be equal to 3, to make the equation true.

Given data:

The equation is, .

The given equation is a quadratic equation with an unknown variable g at right hand side (RHS).

To obtain the value of unknown variable, solve the left hand side (LHS) of the given equation as,

Now, compare the coefficients of each variable from left hand side and right hand side of equation (1) to obtain,

Thus, we can conclude that the value of g should be equal to 3, to make the equation true.
