Calculus
The branch of mathematics that deals with the study of continuously changing quantities, with the use of limits and the differentiation and integration of functions of one or more variables, is called Calculus. Calculus analyzes aspects of change in processes or systems that can be modeled by functions. The English physicist, Isaac Newton, and the German mathematician, G. W. Leibniz, working independently, developed calculus during the 17th century.

If you mean ((-2) x (-6)) - (3 x (-21)) then it equals 75.
Hope this helps!
If: y = 4x^2 -2x -1 and y = 3x-2x^2 +5
Then: 4x^2 -2x -1 = 3x -2x^2 +5
Transposing terms: 6x^2 -5x -6 = 0
Dividing all terms by 6: x^2 -5/6 -1 = 0
Completing the square: (x-5/12)^2 = 169/144
Square root both sides: x-5/12 = -13/12 or 13/12
Adding 5/12 to both sides: x = -2/3 or 3/2
Substitution of x into original equations intersections are at: (-2/3, 19/9) and (3/2, 5)
How many years would it take to count out 60 billion dollars?
well it dapends how fast u count but i can count out 120 in a min so 60 billion/120=ur aunswer
How do you solve x raised to the power of 36?
x raised to the power 36 is x36. Without a value for x, there is nothing to solve!
Where is the center of the circle given by the equation x - 3 2 plus y plus 2 2 equals 9?
(3, -2) You find the center by taking the opposite of the numbers added to the X and to the Y.
What is the range of y equals negative 2x squared plus x?
y = -2x² + x
y = -2 [ x² - (x/2) ]
y = -2 [ x² - (x/2) + (1/4) ] + (1/2)
y = (1/2) - 2[ x - (1/2) ]² ≤ (1/2)
Hence, the Range of y is : -∞ < y ≤ (1/2).
It can be written as the interval ( -∞, 1/2 ]. ........ Ans.

X2 plus 2X equals 8 completing the square?
I think this is how you do it:
x2+2x = 8
x2+2x+(1/2*(2))2 = 8 + (1/2*(2))2
x2+2x+1=8+1
(x+1)2 = 9
SQ.ROOT [(x+1)2 = 9]
x+1 = 3 and x+1 = -3
so,
x=2 and x=-4
How do you isolate y in x plus 2y equals 12?
subtract x from both sides
divide each term by 2.
y=-1/2 x+6
What is the ordered pair of 6x-8y plus 6 equals 36 6y equals 4x-24?
It is: x = -3 and y = -6 or as (-3, -6)
How do you solve this equation -6 equals x over 12?
-6=x/12
The first and only step is to multiply both sides by 12. This gives us x on the right hand side and -6x12 on the left, which simplifies to -72
Thus -72=x
And so x is negative 72.
What is the volume of 30 inches x 30 inches?
The volume is zero.
"30 inches by 30 inches" is a flat, square place, on a table, a piece of paper,
or the ground. You can't put anything in it because it has no "in" .
