<u>Absolute Value:</u>
In mathematics, the absolute value or modulus |x| of a real number x is the non-negative value of x without regard to its sign. Namely, |x| = x for a positive x, |x| = −x for a negative x, and |0| = 0. For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3.
Answer:
Step-by-step explanation:
Given the sets F and H of real numbers defined as given:
F={w | w>3}
H={w | w>6}
To write a set in interval notation, we use these brackets, ( ) for < or > while we use [ or ] for 
.
Since our sets are defined by strict inequalities(< or >)
In interval notation
<span>i think you mean discriminant in part A

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
