The factors of the trinomial to the given quadratic expression are (x+1) and (x-4)
<h3>Factoring quadratic equation</h3>
Given the quadratic equation below
f(x) = x^2 - 3x - 4
Factorize
f(x) = x^2 - 4x + x - 4 = 0
f(x) = x(x - 4) + 1(x - 4) = 0
(x+1)(x-4) = 0
Hence the factors of the trinomial to the given quadratic expression are (x+1) and (x-4)

It's true
collinear means they are on the same line so ST=SU
so if ST= 50 then SU=50 making T the midpoint of line that is 100
