2x² + 7x + 6=0?My preferred method of solving quadratics is by use of the quadratic equation: x = (-b+(or)- the square root of b^2 - 4ac)/2a
In this case a=2, b=7 and c=6
If you substitute in the values to the formula I believe you get:
x= (-7 +or- the square root of … Read more
6y + y +7x + x - + 4z?Are you looking to simplify? If you are...
6y + y = 7y
7x + x = 8x
- + [number] or + - [number] = - [number]
Therefore, 6y + y +7x + x - + 4z = 7y + 8x - 4z.

Well, with the Common Core math that's being taught, the total is actually 3. Thanks for spamming the site because you're bored.

y = ( 3 + 2x - x² )³
Using power and chain rule we get:
dy/dx = 3(3 + 2x - x²)² × d/dx (3 + 2x - x²)
= 3(2 - 2x)( 3 + 2x - x² )²
It's a quadratic equation so factor out it. Break the 7x in two terms 4x+3x and rewrite.
2x² + 7x + 6 = 0 ⇒ 2x² + 4x + 3x + 6 = 0
Now, take 2x common from first two terms and 3 from last two terms
⇒ 2x(x + 2) + 3(x + 2) = … Read more
Ones = 0
Tens = 00
Hundreds = 000
Thousands = 0,000
Ten Thousands = 00,000
Hundred Thousands = 000,000
Millions = 0,000,000
Ten Millions = 00,000,000
Hundred Millions = 000,000,000
Billions = 0,000,000,000
Ten Billions = 00,000,000,000
Hundred Billions = 000,000,000,000
Trillions = 0,000,000,000,000
14.3 trillions = 14,300,000,000,000
The same as you did in your question.
