Answer:
x=±1. are the factors of the quadratic equation.
Step-by-step explanation:
Given quadratic expression, f(x)=-12x - 2x + 60x² +14x-60
Rearranging and adding the terms in the expression and equating to zero.
f(x)= 60x² -60=0
60(x² - 1) =0
The zero product property states that if the product of a⋅b=0 then either a or b equal zero or both of them must be equal to zero. This basic property helps us solve the quadratic equations like (x+2)(x-5)=0 where x =-2,5.
from the zero product property we can infer that 60≠0⇒x² - 1=0
⇒(x+1)×(x-1) = 0
⇒x=±1.
Therefore, x=±1. are the factors of the quadratic equation.
4(p - 7) = 44
First distribute the 4 over the parentheses
4p - 28 = 44
Add 28 to both sides:-
4p = 44 + 28
4p = 72
Divide both sides by 4:-
p = 72/4
p = 18 (answer)
Answer:
2. Weather forecasts are difficult to trust
Step-by-step explanation:
Words like thus are preliminar to a conclusion, that is, we use words like thus when we are going to conclude something.
For Example:
The New Englard Patriots have won 6 Super Bowls. Thus, the New England Patriots are a good NFL franchise.
The conclusion is that the Patriots are a good NFL franchise.
In this problem, we have that:
Thus, it is difficult to trust weather forecasts.
The conclusion is:
2. Weather forecasts are difficult to trust
