Answer:
not sure, sorry : p
Step-by-step explanation:
<span>i think you mean discriminant in part A
</span>
Δ=b^2-4ac=256-4*2*3=256-24=232
it is positive so it has two answers.
Part B
you can find Δ
Δ=b^2-4ac=9-4*9*(-2)=81
x1=-3+9/18=6/18=1/3
x2=-3-9/18=-12/18=-2/3
Factor a 3y² out.
3y²(y-3)
Answer:
18.8888888889
Step-by-step explanation:
2 5/6 = 2.83333333333
6 2/3 = 6.66666666667
2 5/6 * 6 2/3 = 2.83333333333 * 6.66666666667
2.83333333333 * 6.66666666667= 18.8888888889
