Respuesta :
He could draw a diagram of a rectangle with dimensions x – 1 and x – 6 and then show the area is equivalent to the sum of x2, –x, –6x, and 6.
Answer:
Step-by-step explanation:
Since Brent uses a rectangle that models the area = (x² - 7x + 6)
Now we will factorize this expression
x² - 7x + 6 = x² - 6x - x + 6
= x(x - 6) - 1(x - 6)
= (x - 1)(x - 6)
Therefore, (x -1) and (x - 6) will represent the sides of a rectangle so that multiplication of the sides will model the area of the rectangle.
