14x^2-17x-6. (^being 14x squared)
zysi [14]
Factor?, if so
if in ax^2+bx+c form then
multiply a and c together
result=z,
find 2 numbers that multiply to get z and add up to get b
 so



14=a
-17=b
-6=c
14 times -6=-84
factor to find what 2 numbers add up to -17
-84=
-2, 42
-3,28
-4,21
-6,14
-7,12

add each up

-2, 42=40 nope
-3,28=25 nope
-4,21=17 yes, becase if -21 and 4 then answer
-6,14=8 nope
-7,12=5 nope

split up -17 into -21 and 4


14x^2-21x+4x-6
group
(14x^2-21x)+(4x-6)
undistribute
(7x)(2x-3)+(2)(2x-3)
revesres undistribute (ab+ac=a(b+c) or (a+b)(c)+(a+b)(d)=(a+b)(c+d))
(7x+2)(3x-3) is factore out form

then set it to zero and do th emath because if xy=0 then assume x and/or y=0 so
7x+2=0
subtract 2
7x=-2
divide by 7
x=-2/7

3x-3=0
add 3
3x=3
divide 3
x=1
x=-2/7 or 1

Answer:

  a.  plane DEA

Step-by-step explanation:

A plane can be named by naming any 3 non-collinear points in the plane, or by using the plane's name as indicated in the drawing.

Here, points in the plane are A, D, E, F, with DEF all on  the same line. So A plus any two points from the line will constitute a name for the plane. Also, this plane is identified with a script M that can be used to name the plane.

M is not an answer choice, but DEA is. So, the appropriate choice is ...

  plane DEA

__

F is a point, not a plane name. C is not on the plane, so cannot be used to name it. 'k' is a line name, not a plane name.
