Answer:
3x² - 9x + 5
Step-by-step explanation:
Given
(5x² - 3x + 4) - (2x² + 6x - 1)
Distribute the first parenthesis by 1 and the second by - 1
= 5x² - 3x + 4 - 2x² - 6x + 1 ← collect like terms
= (5x² - 2x²) + (- 3x - 6x) + (4 + 1)
= 3x² - 9x + 5
Answer:
D) g(x) is shifted 3 units to the left and reflected over the x-axis
Step-by-step explanation:
The reflection -f(x) indicates a reflection in the x-axis. <u>+</u> means that it shifts to the left.
Answer:
ok
Step-by-step explanation:
Answer:
(x+4)(x-2)
Step-by-step explanation:
We need to find two numbers that multiply to -8 and add up to 2. These are 4,-2.
Rewrite the polynomial:
x^2-2x+4x-8
and factor each pair:
x(x-2)+4(x-2) = (x+4)(x-2)
