Find the zeros of y= x2 - 6x - 4 by completing the square.

x = 3 - √13,  3 + √13.

or

-0.61, 6.61  to the nearest hundredth.

Step-by-step explanation:

x^2 - 6x - 4 = 0

(x - 3)^2 - 9 - 4 = 0

(x - 3)^2 = 13

x - 3 = +/-√13

x = 3 - √13,  3 + √13.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
