What is the solution to x2 plus 2y-6x plus 8y-1 equals x2-y2 plus 4x-6y-1?
x2 + 2y - 6x + 8y - 1 = x2 - y2 + 4x + 6y - 1 y2 - 10x + 4y = 0 y(y+4) = 10x It cannot be solved completely because with two variables (x and y) you need two independent equations for a full solution.
When x equals 5 and y equals 2 find the value of x2 plus 2y?
x2 + 2y = 52 + 2*2 = 25 + 4 = 29
What is the implicit form and explicit of the function x2 plus 2y equals 5?
Implicit: x2 + 2y = 5 Explicit : y = (5 - x2)/2
What is x2 plus 4x plus 4 equals 25?
x2+4x+4 = 25 x2+4x+4-25 = 0 x2+4x-21 = 0 (x+7)(x-3) = 0 x = -7 or x = 3
Can you put the equation x2 plus 4x plus 10 equals 3 in the form ax2 plus bx plus c equals 0?
x^2+4x+7
