To determine To solve: The equation x + 4 + 8 = x . Explanation The given equation is x + 4 + 8 = x . Isolate the radical by subtracting 8 from both sides of the equation as follows. x + 4 + 8 − 8 = x − 8 x + 4 = x − 8 Take square on both sides as follows. ( x + 4 ) 2 = ( x − 8 ) 2 x + 4 = x 2 + 64 − 16 x x 2 − 17 x + 60 = 0 ( x − 12 ) ( x − 5 ) = 0 On further simplification, x − 12 = 0 or x − 5 = x = 12 or x = 5 Therefore, the solution of equation is x = 12 or x = 5 . Check the solution by substituting x = 12 in x + 4 + 8 = x

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
