Set A or B refers to the union of A and B, in other words how many element there are in TOTAL. We are told Set B has 69 elements, but that 13 of them overlap with Set A. This means Set B has 69-13=56 unique elements, and all others are therefore part of set A. If there are 107 elements in total, Set A has 107-56=51 elements.

Can someone give me the answers to this or how to find the answers to it?
faltersainse [42]

the discriminant formula is b^2-4ac

so plug the values from each equation into the formula and solve, the result is the value of the discriminant

if the number is negative, there are no real roots/x-int

if it is 0 there is one real root/x-intercepts

if it is positive it has 2 real roots/x-int

and to find the actual solutions you have to plug the values into the quadratic formula
