Answer:
- x³ - 15x² - 61x - 36
Step-by-step explanation:
Given
(x² - 5x - 4)(x² + 4x + 9)
Each term in the second factor is multiplied by each term in the first factor, that is
x²(x² + 4x + 9) - 5x(x² + 4x + 9) - 4(x² + 4x + 9) ← distribute parenthesis
= + 4x³ + 9x² - 5x³ - 20x² - 45x - 4x² - 16x - 36 ← collect like terms
= - x³ - 15x² - 61x - 36

Answer:
x >
Step-by-step explanation:
Change the less than sign to an equals sign so we can solve for x
(4-3x)-6 = -4
Reorder the numbers in the parentheses
(-3x+4)-6 = -4
Get rid of the parentheses and combine like terms
-3x-2 = -4
Add 2 to both sides
-3x = -2
Divide both sides by -3
x =
Bkuz you want it to be less than, change the equals sign to a greater than symbol bkuz of the negatives
