Step-by-step explanation:
3x² + 5x + 2 = 0
(a)
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × 2 = 6 and sum = 5
The factors are + 3 and + 2
Use these factors to split the x- term
3x² + 3x + 2x + 2 = 0 ( factor the first/second and third/fourth terms )
3x(x + 1) + 2(x + 1) = 0 ← factor out (x + 1) from each term
(x + 1)(3x + 2) = 0
(b)
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
3x + 2 = 0 ⇒ 3x = - 2 ⇒ x = -
Answer: Option 3
Step-by-step explanation:
You can make equivalent fractions by multiplying or dividing both top and bottom by the same amount. You only multiply or divide, never add or subtract, to get an equivalent fraction.

Answer:
Marginal revenue equation is 0.1262x +1.3878 the production of the given number of bushels.
Step-by-step explanation:
Explanation:-
Given the revenue equation is R(x)=0.0631x^2 +1.3878x +2.1447
where 'x' is in hundreds of millions of bushels.
marginal revenue formula is calculated by dividing the change in quantity sold
Now differentiating R(x) with respective to 'x' , we get
<u>conclusion</u>:-
Marginal revenue equation is 0.1262x +1.3878 where 'x' the production of the given number of bushels.
You do 24/4= 6
You divide I hope this helps
I think it that but if not I am sorry good luck
