Answer:

x = -3

Step-by-step explanation:

Add 1 to both sides to, this gives you 4x = -12. then divide both sides by 4, which would give you x = -3.

Please I need answers Factorize x²-6x+9

miskamm [114]

Answer:

The factors of the given equation are:

$x^2-6x+9=(x-3)(x-3)=(x-3)^2$

Step-by-step explanation:

We have :

$x^2-6x+9$

Using middle term splitting theorem to factorize the expression :

$x^2-3x-3x+9$

$x(x-3)+(-3)(x-3)$

$(x-3)(x-3)$

$x^2-6x+9=(x-3)(x-3)=(x-3)^2$

The factors of the given equation are:

$x^2-6x+9=(x-3)(x-3)=(x-3)^2$

What is the equation of the circle that has its center at -26,120 and passed through the origin

OlgaM077 [116]

well, first off let's check those two points, we know it's centerd at (-26 , 120) and we also know it passes through (0 , 0), so the distance between those two points is its radius

$~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{0}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{-26}~,~\stackrel{y_2}{120})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ \stackrel{radius}{r}=\sqrt{(~~-26 - 0~~)^2 + (~~120 - 0~~)^2} \implies r=\sqrt{(-26)^2 + (120 )^2} \\\\\\ r=\sqrt{( -26 )^2 + ( 120 )^2} \implies r=\sqrt{ 676 + 14400 } \implies r=\sqrt{ 15076 } \\\\[-0.35em] ~\dotfill$

$\textit{equation of a circle}\\\\ (x- h)^2+(y- k)^2= r^2 \hspace{5em}\stackrel{center}{(\underset{-26}{h}~~,~~\underset{120}{k})}\qquad \stackrel{radius}{\underset{\sqrt{15076}}{r}} \\\\[-0.35em] ~\dotfill\\\\ ( ~~ x - (-26) ~~ )^2 ~~ + ~~ ( ~~ y-120 ~~ )^2~~ = ~~(\sqrt{15076})^2 \\\\[-0.35em] ~\dotfill\\\\ ~\hfill (x+26)^2+(y-120)^2 = 15076~\hfill$
