Answer:
x² - x - 12 = (x - 4)(x - 3)
Step-by-step explanation:
We have the trinomial x² - x - 12.
We have to show two binomials to be factors of this above trinomial.
For this first we have to factorize the trinomial.
Now, x² - x - 12
= x² - 4x + 3x - 12
= x(x - 4) + 3(x - 4)
= (x - 4)(x - 3)
So the binomials are (x - 4) and (x - 3) that are factors of the trinomial x² - x - 12. (Answer)

Answer:
Step-by-step explanation:
Use midpoint formula to find the coordinates of each midpoint.
(x, y) = (½ (x₁ + x₂), ½(y₁ + y₂))
Coordinates of D:
(x, y) = (½ (4 + 2), ½(6 + -2))
(x, y) = (3, 2)
Coordinates of E:
(x, y) = (½ (4 + -2), ½(6 + -4))
(x, y) = (1, 1)
Slope of DE:
m = Δy / Δx
m = (2 − 1) / (3 − 1)
m = 1/2
Slope of BC:
m = Δy / Δx
m = (-2 − -4) / (2 − -2)
m = 1/2
Therefore, DE is parallel to BC.
