I'll assume they are. This will give
4(x + 3)(x - 1)
-----------------
(x + 3)(x^2 + 3x)
Th (x + 3) ' s cancel ou so we are left with:_
4x - 4
--------
x^2 + 3x
- which is A.
Answer:12 is the mean
Step-by-step explanation: Just find the middle number
Answer:
y = - 2x² - 2x + 40
Step-by-step explanation:
Standard form of a quadratic is y = ax² + bx + c : a ≠ 0
Given
y = - 2(x + 5)(x - 4) ← expand factors using FOIL
= - 2(x² - 4x + 5x - 20)
= - 2(x² + x - 20) ← distribute parenthesis by - 2
= - 2x² - 2x + 40 ← in standard form
Ok first I need to know what number is multiplied by four and yea
