Sarah has 36 crayons she can pack them in boxes of 10 crayons or as single crayons what are all the ways sara can pack the crayons

answer:

1^2 = 1

2^2 = 4

3^2 = 9

n^2 = 10000 --> n = 100

the number 10000 is on place 100.

answer: discriminant is 36. there are two real solutions (both different)

explanation:

the equation 1x^2 - 4x - 5 = 0 is in the form ax^2 + bx + c = 0. we see that

a = 1, b = -4, c = -5

so the discriminant is

d = b^2 - 4ac

d = (-4)^2 - 4()

d = 16 + 20

d = 36 is the discriminant

the discriminant is positive, so there are two different solutions. the solutions are both real.

note: because the discriminant is a perfect square, this means that the two solutions are rational (ie fractions of whole numbers).
