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:

Answer:
192.00
Step-by-step explanation:
All you have to do is multiple then just multiple
8 X 24.00
which will leave you with 192 then that's your answer 192.00 also add the .00 part because there are no change left
If your question is "what time was it before the elapsed time", then the answer will be 9:38. All you have to do is to deduct the time by 30 minutes based on your clock, and you will be able to get the answer right away. Also, if you add 9:38 by 30 minutes, you will get 10:08 as well.
Step-by-step explanation:
the area of a parallelogram is
baseline × height
which is in our case
9 × 7 = 63 m²
