What is y to the 8th power as an product in four different was with only positive exponents?
y6 x y2 y4 x y4 y2 x y2 x y4 y2 x y2 x y2 x y2
Convert x2 plus y2 equals 2x?
What do you want to convert it to? x2 + y2 = 2x If you want to solve for y: x2 + y2 = 2x ∴ y2 = 2x - x2 ∴ y = (2x - x2)1/2 If you want to solve for x: x2 + y2 = 2x ∴ x2 - 2x = -y2 ∴ x2 - 2x + 1 = 1 - y2 ∴ (x - 1)2 = 1 - y2 ∴ x - 1 = ±(1 - y2)1/2 ∴ x = 1 ± (1 - y2)1/2

What is the following equation if a circle whose center is at the origin and whose radius is SQ RT of 5?
x2 + y2 =x2 + y2 = 5x2 + y2 = 10x2 + y2 = 25
How do you multiply open parenthesis Y to the second power minus two close parenthesis open parenthesis two Y plus five close parenthesis?
(y2 - 2) (2y + 5)This is a fine opportunity to apply the FOILmethod of algebra.'FOIL' is a memory word to help you remember how to multiply two binomials ... exactly the task presented here.'FOIL' stands for 'First', 'Outside', 'Inside', 'Last'. Those are the four pairs of terms you have to multiply, and then add the four products together.First: (y2...) (2y...) = 2y3Outside: (y2...) (... +5) = 5y2Inside: (... -2) (2y... ) = -4yLast: (... -2) (... +5) = -10Add all 4 results, and there you have it: 2y3 + 5y2- 4y - 10
What is y2 plus y2?
y2 + y2 = 2y2
Multiply and simplify y-6 y-4?

Is the product of a complex number and its conjugate a real number?
Yes. If you multiply X + iY by X - iY you get X2 + Y2. The imaginary parts cancel out.

4x-y2 = 2
How do you write an equation given a slope and a point?
Using the (surprise, surprise) "point-slope formula". The slope of a line is m = (y2 - y1)/(x2 - x1). If we let y2 and x2 be the variables x and y and multiply by y, we get y - y1 = m(x - x1).
What is 66-3y plus y2 from 88 plus 5y-y2?

Convert x2 plus y2 equals 2x?
What do you want to convert it to? x2 + y2 = 2x If you want to solve for y: x2 + y2 = 2x ∴ y2 = 2x - x2 ∴ y = (2x - x2)1/2 If you want to solve for x: x2 + y2 = 2x ∴ x2 - 2x = -y2 ∴ x2 - 2x + 1 = 1 - y2 ∴ (x - 1)2 = 1 - y2 ∴ x - 1 = ±(1 - y2)1/2 ∴ x = 1 ± (1 - y2)1/2
