Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals", "squared" etc. There are no symbols visible between x2 and y2 (which, I suspect, should be squares.
Second, the question does not contain an equation since there is no equality sign. There is only an expression.

The formula for a standard form is: Ax + By = C. You should never have a fraction in the x or y places.. Quadric: x2 (exponential ex 22, 562, 472) + x(variable ex 2x, 56x 47x) + a number(ex 2, 56, 47) so x2 + x2 + a number
x2 - 10x - 6 = 2x + 1 Subtracting 2x + 1 from both sides gives: x2 - 12x - 7 = 0
Th e two points are X1,Y1 and X2, Y2 slope, m, is y2-y1 divided by x2-x1 then standard form is y = mx +b plug in y2 for y and x2 for x and solve b or plug in y1 for y and x1 for x and solve b
Standard equation for a circle centred at the origin is x2 + y2 = r2 where r is the radius of the circle. If you increase the size of the circle then the radius must increase, so r2 will be larger. eg a circle of radius 2 has the equation x2 + y2 = 4, if the radius increases to 3 then the equation becomes x2 + y2 = 9
It is: x2-10x+21 = 0 and the value of x is 3 or 7 when solved
