Answer:
x-4 and x+8
Step-by-step explanation:
Factoring a quadratic equation of the form x^2+bx+c:
Divide b into two numbers p and q, so that p+q = b and p*q = c
8 + (-4) = 4 = b
8 * (-4) = -32 = c
x^2+8x-4x-32
Factor by grouping
(x^2+8x)+ (-4x-32) =
x*(x+8) + -4* (x+8) = (x-4)(x+8)
Ok... let's say, the pieces are "a", "b", and "c".
"a" being the shortest and "c" being the longest
we know the longest is 38 more than the shortest, so
c = a + 38
and the third piece,
b,
is half the longest, or
c/2
we know the three pieces come from the 102in ribbon, thus
a + b + c = 102

solve for "a".
c = a + 38, and b = c/2
