Step-by-step explanation:
Answer:
B
Step-by-step explanation:
12x² - 157x - 40
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 = 12 × - 40 = - 480 and sum = - 157
The factors are + 3 and - 160
Use these factors to split the x- term
12x² + 3x - 160x - 40 ( factor the first/second and third/fourth terms
= 3x(4x + 1) - 40(4x + 1) ← factor out (4x + 1) from each term
= (4x + 1)(3x - 40) ← in factored form → B
Answer:
{x | x R, x > -5}
Step-by-step explanation:
Given:
Add 5 both sides, we get
Therefore, the solution is 
where, x is a real number.
So, {x | x R, x > -5} is the correct answer.
