Step-by-step explanation:
We khow the sum and the product of the zeroes of this quadratic polynomial
Here is a trick :
when we khow the sum S and the product P ofvtwo numbers we can find them by solving :
x²-Sx+p=0
here S= -8 and P=12
so:
x²+8x+12=0
Let Δ be the discrminant of this equation: a= 1 , b= 8 and c=12
Δ= 8²-4*12 =16
the zeros are:
(-8-4)/2= -6
(-8+4)/2 = -2
verify:
-6+(-2)= -8
-2*(-6)= 12
now the polynomial quadratic is:
(x+6)(x+2)

Step-by-step explanation:
GIvn that Ming needs 1/2 pint of red paint for an art project
The 6 jars he has, have the following red paint in them
A. 2/3 pint
B.1/4 pint
C.4/6 pint
D.3/4 pint
E. 3/8 pint
F.2/6 pint
Since he want 1/2 pint he can use only jar B two times
First pour jar B contents equal to 1/4 pint to a new empty jar.
Now he can pour from A 1/4 pint to B, and then again use that
So altogether he gets 1/2 pint of red paint.
