Answer:
Short Answer: B
Step-by-step explanation:
Using synthetic division to break this down a little, we get from your hint, the following
-5 || 1 - 4 -21 100 - 100
-5 45 -120 100
======================
1 -9 24 -20 0 = x^3 - 9x^2 + 24x - 20
We can do this again, this time using 5
5 || 1 - 9 24 - 20
5 -20 20
===========================
1 -4 4 0 = x^2 - 4x + 4
h(x) = x^2 - 4x + 4 factors into
h(x) = (x - 2)(x - 2)
The final result is f(x) = (x + 5)(x - 5)(x - 2) (x - 2)
which is B
Answer: It was the “high light” of his career
Step-by-step explanation:
Correction:
1⟩
Given equation is x²-3x = 4
⇛ x²-3x -4 = 0
⇛ x²+x-4x-4 = 0
⇛ x(x+1)-4(x+1) = 0
⇛ (x+1)(x-4) = 0
⇛ x+1 = 0 or x-4 = 0
⇛ x = -1 or x = 4
2.⟩
Given equation is x²+4x+4 = 0
⇛ x²+2x+2x+4 = 0
⇛ x(x+2)+2(x+2) = 0
⇛ (x+2)(x+2) = 0
⇛ x+2 = 0
⇛ x = -2
