Answer:

Step-by-step explanation:

$x^{2}$ - 6x +5 = 0

$x^{2}$ - 6x + 9 -9 +5 = 0

[ $x^{2}$ - 6x + 9] - 4 =0

$(x -3)^{2}$ -4 = 0

$(x -3)^{2}$ = 4

(x-3) = $\sqrt{4}$ or (x-3) = - $\sqrt{4}$

(x-3) = 2 or (x-3) = -2

x = 5 or x = 1

therefore, sum of these solutions is 5+1 = 6

How do you find the equation of a line if it is like 2x-3y=6?<br> Please show work

tatiyna

Answer:y=2/3x-2

Step-by-step explanation:

you need to get “Y” by itself therefore you subtract 2x on each side you will end up with -3y=-2x+6 then to get “Y” by itself you divide by -3 on both side and since there is a negative 2 on the other side a negative and a negative makes a positive and then you divide the 6 by -3 , that will give you y=2/3x-2
