Use the remainder theorem to factor
2 answers:
Answer:
A is the correct choice
Step-by-step explanation:
Use synthetic division to check:
x^3-3x^2-13x+15 / x-5
5 | 1 -3 -13 15
5 10 -15
_________
1 2 -3 0
This means x^2+2x-3 with no remainder which means A works
Answer:
A) (x2 + 2x - 3)(x - 5)
Step-by-step explanation:
x³ - 3x² - 13x + 15
x = 5
5³ - 3(5)² - 13(5) + 15 = 0
So 5 is a root and x-5 is a factor
Since the constant is 15, it has to be
A) (x2 + 2x - 3)(x - 5)
(-5) × (-3) = 15

Step-by-step explanation:
9(-2) =-2(-2)+3(-2)-5
9(2)=-2(4)-6-5
9(0)=-2(4)-6-5
0=-8-11
