Find the term that must be added to the equation x2 6x=1 to make it into a perfect square.

andrezito [222]

The value added to the equation $$x^2-6x=1$ exists $$x^2-6x+9=10$ .

<h3>What is a perfect square?</h3>

A perfect square exists as a number that can be described as the product of an integer by itself or as the second exponent of an integer.

The perfect square trinomial exists

$(a$ ± $b)^2$ = $a ^2$ ± 2ab + $b ^2$

$$x^2-6x=1$

$x^2-2*3x=1$

then $$2ab = 2 * 3*x = 2 * x *3$

The value of a = x and b = 3

$$b^2=3^2=9$

$$x^2-6x+9=1+9$

$$x^2-6x+9=10$

The value added to the equation $$x^2-6x=1$ exists $$x^2-6x+9=10$ .
