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.
Answer:
x ≈ 20.42, y ≈ 11.71
Step-by-step explanation:
Using the cosine ratio on the right triangle on the right, that is
cos20° = 
= 
Multiply both sides by y
y × cos20° = 11 ( divide both sides by cos20° )
y = 
≈ 11.71
Using the sine ratio on the right triangle on the left, that is
sin35° = 
= 
= 
Multiply both sides by x
x × sin35° = 11.71 ( divide both sides by sin35° )
x = 
≈ 20.42
Answer:
6-7-8-9-10-11-12-13-14-15 etc...
Step-by-step explanation:
any number that is equal to 6 or greater than 6 is a possible value for x.
My best Guess is
1.282 for upper . , -1.282 for lower.
Hope this Helps
