Answer:
Step-by-step explanation:
The expression given can be rewritten as:
Because +(-n) is just -n. Then, combine like terms to get:
Substitute 
for x to get:
Which can be rewritten as:
Which is:
. as a mixed number
Hope this helps :)
The correct answer is c (4,-5)
Answer:
Yes You Are Correct :)
Step-by-step explanation:
Answer:
(x - 2)(x - 3)
Step-by-step explanation:
The student factored the expression as (x - 1)(x - 6)
The error made is that - 6x and - 1x to not sum to - 5x
Given
x² - 5x + 6
Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (- 5)
The factors are - 2 and - 3, since
- 2 × - 3 = + 6 and - 2 - 3 = - 5, thus
x² - 2x - 3x + 6
= x(x - 2) - 3(x - 2)
= (x - 2)(x - 3)
