The cross-section of a cube, if the slice is made parallel to one of the faces, would be a square congruent to the face of the cube.
B is a factor of the equation above because if you do 3a^2 + 17a + 10 you would get (3a +2) (a+5)
First factor top
x^2-15x+36
what multipilies to 36 and adds to -15
-3 and -12
(x-3)(x-12)
bottom
5x-60
factor out 5
(5)(x-12)
now we have
