Rewrite the equation by completing the square g(x) = x^2 - x - 6
borishaifa [10]

Answer:

g(x)=x2−x−6g(x)=x2-x-6

Set x2−x−6x2-x-6 equal to 00.

x2−x−6=0x2-x-6=0

Solve for xx.

Tap for fewer steps...

Factor x2−x−6x2-x-6 using the AC method.

Tap for more steps...

(x−3)(x+2)=0(x-3)(x+2)=0

If any individual factor on the left side of the equation is equal to 00, the entire expression will be equal to 00.

x−3=0x-3=0

x+2=0x+2=0

Set x−3x-3 equal to 00 and solve for xx.

Tap for more steps...

x=3x=3

Set x+2x+2 equal to 00 and solve for xx.

Tap for more steps...

x=−2x=-2

The final solution is all the values that make (x−3)(x+2)=0(x-3)(x+2)=0 true.

x=3,−2

Indicate the equation of the line meeting the given conditions. Please put the equation in standard form. Containing A (1, 3) an
wolverine [178]
A line through two points A, B can be found by the point-slope form of the formula:

(y-ya)=m(x-xa)............(1)
and 
m=(yb-ya)/(xb-xa).......(2)

where A(xa,ya), B(xb,yb) and m is the slope between points A & B.

Substituting
A(xa,ya)=A(1,3)
B(xb,yb)=B(0,2)

From (2)
m=(yb-ya)/(xb-xa)
=(2-3)/(0-1)
=-1/(-1)
=1

Substitute in (1)  : (y-ya)=m(x-xa)
y-3=1(x-1)
Distribute and simplify
y=x-1+3=x+2
or
y=x+2  .................(3a) equation required in slope-intercept form

x-y+2=0...............(3b) equation in standard form
