Answer:
x = 1 / 3
x = -1.5
Step-by-step explanation:
First move everything onto one side.
6x^2 + 7x - 3 = 0
Divide by 6:
x^2 + 7/6x - 0.5 = 0
Now, you can move the 0.5 to the other side because it is determined that this is not factorable.
x^2 + 7/6x = 0.5
Now you have to complete the square.
Take 1 / 2 of 7 / 6 and square it.
49 / 144
x^2 + 7/6x + 49/144 = 0.5 + 49/144
(x + 7 / 12)^2 = 121 / 144
Square root:
x + 7 / 12 = ±11 / 12
x = 1 / 3, x = -1.5
Im sorry wish i could help but the equation is a little confusing give me a few moments and i will figure out the answer okay?
Answer:
The answer is -1
Step-by-step explanation:
f(x) = 2x³ + x² - 3x - 1
f(1) = 2(1)³ + (1)² - 3(1) - 1
f(1)= 2 + 1 - 3 - 1
f(1)=3-3-1
f(1)=0-1
f(1)= -1
Thus the answer is -1 ....
Answer:

This would be much easier to answer if you would use a conventional representation of ordered pairs:
... (-1, -2) instead of "begin ordered pair negative 1 comma negative 2 end ordered pair"
Answer:
I also need help with this one. I don't know what it is. I don't fully understand the two column proof. I might figure it out and edit this answer or put it in comments.
