Use the definition of continuity and the properties of limits to show that f(x)=x^2-49/(x^2+6x-7)(x^2+14x+49) is continuous at x=5

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

b
