Write the equation of the circle in standard form :
a) x^2 - 10x _ y^2 - 8y = -32
--------
I'll assume the _ should be a +
x^2 - 10x + y^2 - 8y = -32
Complete the square for x and y
%28x%5E2-10x%2B25%29+%2B+%28y%5E2-8y%2B16%29+=+-32+%2B+25+%2B+16+=+9
%28x-5%29%5E2+%2B+%28y%2B4%29%5E2+=+3%5E2
=============================================
b) x^2 - 2x + y^2 - 4y - 3 = 0
Do it the same way.
