Factor the coefficients:
-12=(-1)(3)(2^2)
-9=(-1)(3^2)
3=3
The greatest common factor (GCF) is 3
Next we find the GCF for the variable x.
x^4
x^3
x^2
The GCF is x^2.
Next GCF for variable y.
y
y^2
y^3
the GCF is y
Therefore the GCF is 3x^2y
To factor this out, we need to divide each term by the GCF,
(3x^2y)(−12x4y/(3x^2y) − 9x3y2/(3x^2y) + 3x2y3/(3x^2y) )
=(3x^2y)(-4x^2-3xy+y^2)
if we wish, we can factor further:
(3x^2y)(y-4x)(x+y)
I know this doesn't help but i'm on the same thing and i just don't know
The simplest answer is 0 if u actrually do the work if u have to sneak a calculator in XD
Answer: 2/3ft or C
Step-by-step explanation: Solve for b in the area of a triangle equation, A=1/2bh. Multiply 1/2 by 2 on both sides to cancel it: A(2)=bh. Divide both sides by h: 
=b
A = 2/5
h = 6/5
b = ?
Next, we can plug the numbers into this equation: 
=b
Multiply 2 and 2/5: 4/5 / 6/5
Take the reciprocal of 6/5: 4/5 x 5/6 = 
÷ 
= 
Answer:
2
Step-by-step explanation:
In this case, you have to substitute the w for -1, and then do the operation:
-6( -1 )^2 + 13( -1 ) + 21
-6( 1 ) - 13 +21
-6 -13 + 21
-19 + 21
2
