x= 20 x =-5
Step-by-step explanation:
x^2 – 15x – 100 = 0.
What two numbers multiply to -100 and add to -15
-20 * 5 = -100
-20 +5 = -15
(x-20) (x+5) =0
Using the zero product property
x-20 =0 x+5 = 0
x= 20 x =-5
This means that 2/5 is white and 3/5 is whole wheat, so 2/5 of 10=4 cups of white, 3/5 of 10=6 cups of whole wheat.
