I will assume that you meant:
(x+4)/(-3x^2+12x+36) factor the denominator...
(x+4)/(-3(x^2-4x-12))
To factor a quadratic of the form ax^2+bx+c you need to find two values, j and k, which satisfy two conditions...
jk=ac=-12 and j+k=b=-4 so j and k must be 2 and -6 and the factors are then:
(x+2)(x-6) so we are now left with:
(x+4)/(-3(x+2)(x-6))
The only restriction on this function is that division by zero is undefined, so x cannot equal -2 or 6
Answer:
- 2x³
Step-by-step explanation:
f(x) - g(x)
= - x - (2x³ - - x) ← distribute parenthesis by - 1
= - x - 2x³ + + x ← collect like terms )
= - 2x³
Answer: 11, 30
Step-by-step explanation:
Given
There were a total of 41 national battlefields and national memorials
Suppose there are national battlefields
So, national memorials are
The sum of the two must be 41
So, there are 11 national battlefields and national memorials.
