Answer:

Negative

Step-by-step explanation:

A negative plus a negative (negative minus a positive) will give you a negative. -1.69 + (-1.69) = -3.38

-3.38 is a negative, therefore the answer is negative.

The equation in required form is: $(x-4)^2 = 3$

Step-by-step explanation:

Given equation is:

$x^2-8x+13=0$

to write the equation in $(x-a)^2 = b$ form where a and b are integers

subtracting 13 from both sides

$x^2-8x+13-13=0-13\\x^2-8x = -13$

To complete the square:

2.x.b = 8x

b = 8x/2x = 4

So adding (4)^2 on both sides

$(x)^2-8x+(4)^2 = -13+(4)^2\\(x-4)^2 = -13+16\\(x-4)^2 = 3$

Hence,

The equation in required form is: $(x-4)^2 = 3$
