Sry I just really need one last answer, it’s rlly important, sry
-1(x+ and -(x+. because -x is same as -1
Answer:
(x - 8)(x + 3)
Step-by-step explanation:
x² - 5x - 24
Consider the factors of - 24 which sum to give the coefficient of the x- term (- 5)
The factors are - 8 and + 3 , since
- 8 × + 3 = - 24 and - 8 + 3 = - 5
Use these factors to split the x- term
x² - 8x + 3x - 24 ( factor the first/second and third/fourth terms )
= x(x - 8) + 3(x - 8) ← factor out (x - 8) from each term
= (x - 8)(x + 3) ← in factored form
Add the two functions together to get
7y=-3
y=-3/7
Then plug in y to either function to solve for x, I’ll just use the left one
15(-3/7)-9x=-9
-45/7-9x=-9
-9x=-18/7
x=18/7/9
x=2/7
