Solve the quadratic equation by completing the square. first chose the appropriate form and fill in the blanks with the correct numbers. then solve the equation. round your answer to the nearest hundredth. if there’s more than one solution separate them with commas. x^2-4x-3=0

(x - 2)^2 = 7

x = 4.65 or x  = -0.65

Step-by-step explanation:

x^2-4x - 3=0

x^2-4x = 3

x^2-4x  + 4 = 3 + 4

x^2  - 4x + 4 = 7

(x - 2)^2 = 7

x - 2 = +-√7

x = 2 +- √7

x = 4.65 or x  = -0.65

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.
