4x+y= x

Move all x term to left side

4x-x+y=0

Subtract 4x from 3x

3x+y=0

Move y term to right side

3x= -y

Divide both sides by 3

X= -y/3

Ok so if it's

4x+y= z solve for x

Move y to right side

4x= -y +z

Now divide both by 4 to get x alone

X= -y/4 + z/4

How do you complete the square to rewrite y= x^ -6x + 15 in vertex form

Vaselesa [24]

Vertex form of a quadratic equation is $y=a(x-h)^{2}+k$
where (h, k) is the vertex.

Our aim is to write the expression $y=x^{2} -6x+15$ in the form
$y=a(x-h)^{2}+k$

$y=x^{2} -6x+15$

$y=x^{2} -2*3*x+15$

$y=(x^{2} -2*3*x+ 3^{2})-3^{2}+ 15$

$y=(x-3)^{2}-9+15$

$y=(x-3)^{2}+6$
